Hi, I need help with this physcis problem. I've gone over it multiple times and can't firgure it out. Anyway you can help? A car, initially at rest, accelerates at a constant rate of 2 m/s2 due east (choose east as the positive direction; round your answer to the nearest meter per second; include units)What is its velocity after 1 second? What is its velocity after 2 seconds? What is its velocity after 3 seconds? What is its velocity after 4 seconds? What is its velocity after 5 seconds? What is its velocity after 9 seconds? If instead a car accelerates at a constant rate of 5 m/s2 due eastWhat is its velocity after 1 second? What is its velocity after 2 seconds? What is its velocity after 3 seconds? If instead a car accelerates at a constant rate of 5 m/s2 due westWhat is its velocity after 1 second?
Standing at the edge of a cliff 30.5 m high,you drop a ball. Later, you throw a second ball downward with aninitial speed of 11.2 m>s. (a) Which ball has the greater increase inspeed when it reaches the base of the cliff, or do both balls speedup by the same amount? (b) Verify your answer to part (a) with acalculation.
Try the following experiment away from traffic: where you can do it Safely. With the car VOU are driving moving slowly on a Straight, level road, shift the transmission into neutral and let the car coast. At the moment the car comes to a complete slop, step hard on the ln.ike and notice what you feel. Now repeal I he same experiment on a fairly gentle, uphill slope. Explain the difference in what a pet son tiding in the car feels in the two cases. (Brian Popp suggested the idea for this question.)
1. Galileo released two bodies of different masses from the Pisa tower to test his theory. Knowing that the height of the tower is 52 m. A) Indicate in the image the characteristics of the movement of a body and deduce its type of movement. B) Write the equations of motion corresponding to the movement of the body. C) Calculate the time it takes to reach the ground. D) How fast will they arrive? Interpret the results. 0.5p E) What speed do we carry halfway? Interpret the results. F) With what speed should we pull up so that the body reaches the ground in 10s. G) Selected and graphic corresponding to the previous movement. Justify your answer.
You decide to flip a coin to determine whether to do your physics or English homework first.The coin is flipped straight up. (a) If the coin reaches a high point of 0.25 m above where youreleased it, what was its initial speed? (b) If you catch it at the same height as you released it,how much time did it spend in the air? Hint: The time it takes the ball to rise equals the time ittakes to fall.
A 19856kg helicopter moved upward with a constant acceleration from text to a height of 491m. The spinning blades create an upward thrust of 378247N that lifts the helicopter into the air. What is the acceleration of the helicopter? (Round to the nearest thousandth if necessary)
What is meant by instantaneous velocity, average velocity and final velocity?Define acceleration, force, energy, potential energy and kinetic energy and write the formula for each.A force is a vector quantity capable of producing motion or a change in motion, that is, a change invelocity or an accelerationWhat are the units of force and energy in CHS, MKS, and FPS units?What is static friction and what is kinetic friction?Explain the law of conservation of energy.
1. Using the terms slope, acceleration, and velocity, explain how you know the rocket launched in the graph above is speeding up. 2. What are the units for the slope of a velocity-time graph? 3. What does the slope of a velocity-time graph represent? 4. What are the units for the area of an acceleration-time graph? 5. What does the area of an acceleration-time graph represent?
Hoping for complete solutions since I’m having a hard time with this. The question is asking for both an instantenous position x(t) and velocity v(t) equations. Pls skip if unsure or not willing to answer the subquestions A-E (these are all connected for one item). Thanks in advanced! Tw‎o bloc‎ks con‎nected by a light horiz‎ontal rope sit at re‎st on a horiz‎ontal, fri‎ctionless surfa‎ce. Block A has mass 15.0 [kg], and b‎lock B has m‎ass m.

1. Marley sprint-cycles for 25s. For the first 10.0s she pearls at the rate of 12.0m/s.Then she slows at 6.00m/s for the next 10s. As she nears the end of the track ,she pearls at a rate of 15m/s for the remaining 5.0s A) sketch Marley’s velocity- time graph for her spring cycle b) Sketch Marley’s position -time graph for her sprint -cycle .Show your calculations
The answer for part b that I have says 200N. I just was not sure how to do it. Should you be using 2 m/s ( Block A) as the velocity in this equation, instead of 1 m/s? Thanks.
(ii). Show on the diagram above, where is the maximum velocity occurs ? (d). Explain (analytically) how the maximum velocity of the bag would change if Brad had used a longer rope to attach his bag to the hook H2 ?
