I need help finding initial ke, and final ke. The Experiment: In this experiment, the muzzle velocity of a projectile launcher will be 1) predicted, 2)measured, and 3) used as an initial parameter to attempt to land a ball on a floor target.1. Remove the ball from the bob and reset the maximum height rule. Place the ball into the gun and loadthe gun by pushing the ball down the muzzle using the dowel. Remember to be consistent with yoursetting.2. When the pendulum is at rest, fire the ball into the pendulum bob. This will cause the pendulum withthe ball inside it to swing up and strike the marker and the highest angle that the bob has swung. Recordthis angle and repeat this procedure four times, recording the maximum angle for each trial.67g20gBallSteelPlastic0₁37.515.0Table 4: Record experimental data below.020338.2 38.014.3 13.50438.614.5Ave. Deflection38.114.3arm mass: 243garm length: 30cm3.

Solve the problem. PROVIDE THE GIVEN, REQUIRED, EQUATION, SOLUTION, AND FINAL ANSWER The charter day of Manila is usually celebrated with a fireworks display. In one of the displays, a shell was shot into the air with an initial speed of 87.0 m/s at an angle of 85.0º above the horizontal. The fuse was timed to ignite the shell just as it reaches its highest point above the ground. Solve for the following: a) height at which the shell explodes; b) time passed between the launch of the shell and the explosion c) horizontal displacement of the shell when it explodes.
Suggest some likely sources of error that could be responsible for the difference between your measured and predicted values for the horizontal distance traveled by the projectile at the different angles used in this experiment. “Human error” is not acceptable without saying specifically what error the human could have made. “Calculation error” is also not acceptable—if you are worried about whether the calculation is correct, consult with your classmates and/or someone you trust to do the calculation correctly. PROCEDURE Part I Place a marble launcher on the table, oriented so it points straight upward (θ = 90°). Pull the launch mechanism back to the first (nearest) launch position and place a marble into the launcher. Practice quickly releasing the launch mechanism and get a sense for the maximum height the marble will reach after it is launched. Hold a meter stick beside the marble launcher so that the zero end is beside the marble. Launch the marble and record the maximum…
the muzzle velocity of a new cannon. It was 289 m/s. Now the cannon is deployed and the military engineers have determined the walls of the fort are 1609 meters away. If the artillery crew aims for 1611 m, the cannonball should hit the center of the wall. At what angle should the artillery crew fire the cannon to hit the walls? (Ignore the height of the cannon and assume the cannonball is fired from ground level. Also, you will need 2sinθcosθ = sin(2θ).)[Using the range equation is UNACCEPTABLE. You must solve the problem from scratch showing all of your work along the way.]

PROVIDE THE GIVEN, REQUIRED, EQUATION, SOLUTION, AND FINAL ANSWER Ariana is throwing pebbles gently up to Aira’s window, and he wants the pebbles to hit the window with only a horizontal component of velocity. Ariana is standing at the edge of a garden 5.75 m below the window and 7.0 m from the base of the wall. How fast are the pebbles going when they hit Aria’s window?
A sandal is dropped from the top of a 17-m-high mast on a ship moving at 1.75 m/s due south. Take the deck of the ship to be y=0 m. Set up a table of knowns for the motion of the sandal relative to the ship. If the quantity is currently unknown, simply enter "unknown". Note that these variables are measured with respect to a coordinate system moving with the ship. a=? m/s^2 Calculate the velocity of the sandal relative to the ship when it hits the deck. Check the sign of the velocity. v=? m/s Calculate the velocity of the sandal relative to a stationary observer on the shore when it hits the deck in terms of unit vector notation. Check your signs. Hint: Relative to a stationary observer on the shore, the vertical motion of the sandal is the same as that measured by an observer on the ship. In addition, the sandal will have a horizontal velocity. What is the horizontal velocity equal to? v= ? m/s i+ ? m/s j

I did a lab based Projectile Motion and they ask me this question Following the definitions of direct and inverse proportionality earlier, discuss why this equation shows that your answers for initial velocity and gravity are correct. * Note that this range equation only works if y0 = yf I think is because of the no air resistance but im not sure can you help me this one I don't want to know if I'm right or wrong?
Bob has just finished climbing a sheer cliff above a level beach and wants to figure out how high he climbed. All he has to use is baseball, a stopwatch, and friend on the ground below with a long measuring tape. Bob is a pitcher and knows that the fastest he can throw the ball is about v_0= 34 m/s. Bob starts the stopwatch as he throws the ball, with no way to measure the ball’s initial trajectory, and he watches carefully. The ball rises and then falls, and after t_1= 0.510 s the ball is once again level with Bob. Bob cannot see we’ll enough to time when the ball hits the ground. Bob’s friend the measures that the ball hit the ground x= 127 m from the base of the cliff. How high above the beach was the ball when it was thrown? A projectile is launched from ground level with an initial speed of 45.5 m/s at an angle of 32.3 degrees above the horizontal. It strikes a target in the air 1.83 s later.

I need help answering this quadratic word problem, thanks in advance At the national spitting competition, contestants were lined up on top of a tall building. The winning projectile was projected off the top of the building in a trajectory defined by the following equation where the height (h) is in metres above the ground and time (t) is in seconds since the projectile was launched. h=-4.9t^2+29.4t+37.9 Show all work when answering the following (no guess and check allowed): a) If the mouth of the person who launched the winning projectile was 1.6 metres above the roof of the building, how tall was the building? b) To the nearest tenth of a second, how long was the projectile in the air before it hit the ground? (Nearest tenth of a second = one decimal place) c) To the nearest tenth of a second, determine how long the projectile was at or above 80m in height.
Applying principles of dynamics (with step by step solutions pls i give 5 stars) The velocity of a particle which moves along the a linear reference axis is given by v = 2—4t— 6t3, t is in seconds while v is in meters per second. Eval-uate the position, velocity and acceleration when t = 3 seconds. Assume an your own initial position and initial point in time. Further, set a variable for position as you see fit.
