Activity 1: Problem Solving Directions: Show your complete solutions for the following worded problems. 1. A flower pot falls a window of a three-storey apartment. How far has it fallen after 2 seconds? What is the pot's velocity after I s of fall? after 2 seconds of fall? 2. A brick falls freely from a high scaffold and hits the ground after 3.5 seconds. How high is the scaffold? What is the velocity of the brick just before hitting the ground? 3. Alice thrown a ball upwards vertically from the roof of a building. The ball leaves her hand at a point level with the roof railing with an upward speed of 15 m/s. On its way back down, it just misses the railing. Find (a) the ball's position and velocity 1.0 s and 4.0 s after leaving her hand; (b) the ball's velocity when it is 5.0 m above the railing; (c) the maximum height reached.

You fire a ball with an initial speed V0 at an angle (ϕ) above the surface of an incline, which is itself inclined at an angle (θ) above the horizontal (Figure below). a. Find the distance, measured along the incline, from the launch point to the point when the ball strikes the incline. b. What angle ϕ gives the maximum range, measured along the incline? Ignore air resistance. c. Since there's no air resistance, this is a problem in projectile motion. The goal is to find the point where the ball's parabolic trajectory intersects the incline. It is best to choose the x-axis to be horizontal and direct to the right, the y-axis to be vertical and direct to the up, and the origin to be at the point where the ball is fired. In the projectile equations, the launch angle α0 is measured from the horizontal. What is this angle in terms of (θ) and (ϕ)?

Ball A is a steel ball and Ball B is a ping pong ball with the same diameter. They are on a frictionless surface with no air movement; having the same e of 0.9 and the same coefficient of friction on the surface of 0.3. (Conceptual Answer, NOT Numerical) How would you find the final velocity of Ball A and Ball B, WITH STEPS AND FORMULAS?

1 Overview Ballistics is the science of projectile motion and impact, phenomena well described by Newtonian mechanics. The number of applications of this type of analysis is staggering, ranging from such mundane issues as automobile accident simulations and optimal golfing to the critical studies of missile defense and space exploration. Somewhat less dramatically, in this project we will use Newtonian mechanics to describe the flight of a sponge dart, light enough so that air resistance will play a critical role. 2 Experimental Data The data for this project was collected by firing sponge darts from a toy gun ($3.99, WalMart). The table below shows a set of measurements for distance traveled (by the projectile) versus angle of inclination of the gun, taking angles of inclination 5, 10, 15, . 85 degrees. The darts were fired from a height of . 18 meters. Angle of 5 Inclination Distance 10 15 20 25 30 35 40 45 4.37 5.23 6.95 7.84 8.17 8.69 8.81 8.99 8.95 Traveled Angle of Inclination…

TASK: Solve the following problems systematically. Show your complete solution. 1. A building's 10th floor (34.5 m high) is blazing with fire. A fire truck arrived at the scene and the fire men shoots water from their hose. The water leaves the hose at the speed of 29 m/s, at an angle of 63° and is held at 0.90 m from the ground. Will the water reach the fire? If so, how far from the building should the hose be so the fire could be put out? 2. A 2 kg ball on a string is rotated about a circle of radius 10 m. The maximum tension allowed in the string is 50 N. What is the maximum speed of the ball?

Hi, I'm confused on how to solve this because the answer I got was separate from the answer key so I do not know if I am right or if I am wrong. This is the question, I would greatly appreciate your assistance. Thank you. A projectile is shot straight up with a velocity of 58.8 m/s.  (Neglect air friction). 1.Calculate the velocity of the projectile 1.5 s after firing.   2.How high above the gun is the projectile 1.5 s after firing?   3. How high is the projectile 9.0 s after firing?   4. Calculate the velocity of the projectile 9.0 s after firing.

Consider a projectile launched from the ground at 18.00 m/s and an initial angle of 57 degrees. 1.) Calculate the x-component of the initial velocity. Record your answer in units of m/s to 4 decimals. 2.) Calculate the y-component of the initial velocity. Record your answer in units of m/s to 4 decimals. 3.) If there is no air resistance, what is the y-component of the acceleration?  Note that g=9.81g=9.81 m/s2. a.) +g+g b.)-g−g c.) Cannot say for sure because it is constantly changing. 4.) If there is no air resistance, what can you say about the x-component of the acceleration? a.) a_x = 0ax​=0 b.) a_x > 0ax​>0 c.) a_x < 0ax​<0 5.) Solve this equation for time. One of the solutions is t=0t=0 s and the other is how how long the projectile stays in the air. Report your answer to 4 decimals. The total time can be found from the equation y=y_i+v_{iy}t+\frac{1}{2}a_y t^2y=yi​+viy​t+21​ay​t2 Using y_i = 0yi​=0 & y = 0y=0, this simplifies to:…
