A tennis ball of mass 0.0631 kg is served. It strikes the ground with a velocity of 54.0 m/s (120 mi/h) at an angle of 22.0° below the horizontal. Just after the bounce it is moving at 53.0 m/s at an angle of 18.0° above the horizontal. If the interaction with the ground lasts 0.0630 s, in what angle does the average force exerted by the ground on the ball act?
3. A tennis ball is served horizontally at A with a velocity va from a height of 2m. It hits th ground at a distance of 7m at B. Determine (i) VA and (ii) VB and θ (assume coefficient of restitution between the ball and the ground to be e 0.7 A VA VB 7m
Problem 2: The tennis ball at A is hit with a horizontal velocity, VA, so that it just clears the net at B before striking the ground at C. Determine: a) The velocity VA b) The distance s where the ball strikes the ground
6. A tennis player strikes a tennis ball with her racket when the ball is at the uppermost point of its trajectory as shown. Just after impact, the velocity of the ball is directed at an angle of 15° above the horizontal. If the 125 gram ball is in contact with the racket for 0.02 sec, and the average impulsive force exerted by the racket on the ball is of magnitude of 200 N and directed at an angle 9°...
A 60 gram tennis ball is dropped from rest from a height of 5.0 m above the ground. A. What is the magnitude of its momentum just before the ball hits the ground if we neglect air resistance? B. What is the impulse on the tennis ball if the rebound speed just after the collision is 80% of the initial speed of the ball you used in part A?
Launch a tennis ball at 20.0 m/sec at 60 degrees above horizontal from the top of a building that is 50.0 meters high. Please show all your work on this page. Keep answers in three significant figures. a. Find the initial horizontal component of the velocity b. Find the vertical component of the velocity c. Find the maximum height, measuring from the ground level d. Find the time to reach the maximum height e. Find the magnitude of vertical velocity...
During her serve, Serena Williams tosses the tennis ball directly upwards, releasing the ball at eye-level (1.75 m above the ground). She strikes the ball with her racquet when it’s 2.75 m above the ground and 1 s after the ball leaves her hand. What is the maximum height of the ball above the ground?
A tennis ball rolls off the edge of a tabletop 0.700 mm above the floor and strikes the floor at a point 1.20 mm horizontally from the edge of the table. Part A.) Find the time of flight of the ball. Part B.) Find the magnitude of the initial velocity of the ball. Part C.) Find the magnitude of the velocity of the ball just before it strikes the floor. Part D.) Find the direction of the velocity of the...
1. A ping pong ball (ball #1, mass of 2g) is held just above a tennis ball (ball #2, mass of 57g) with their centers vertically aligned. When the balls are released, they fall through a vertical distance of 1.27 meters. a) Prove that each ball is traveling at 5.00 m/s just before it hits the ground. The tennis ball (#2) hits the ground and bounces elastically off of it before the ping pong ball (#1) actually hits #2. Since...
part 1 of 3A tennis ball is dropped from 1.79 m above the ground. It rebounds to a height of 1.01 m. With what velocity does it hit the ground? The acceleration of gravity is 9.8 m/s2. (Let down be negative.) Answer in units of m/s. part 2 of 3 With what velocity does it leave the ground? Answer in units of m/s. part 3 of 3 If the tennis ball were in contact with the ground for 0.0126 s. find the acceleration given to the...
