A 900 g rubber ball is dropped from height 17.5 m, and it rebounds to height 5.17 m. Assuming there is no air friction and the average force exerted by the ground is 24.5 N, find the time the ball was in contact with the ground.
A ball falls from height of 19.5 m, hits the floor, and rebounds vertically upward to height of 15.0 m. Assume that mall 0.390 kg. (a) What is the impulse (in kg. m/s) delivered to the ball by the floor? (b) If the ball is in contact with the floor for 0.0400 seconds, what is the average force (in N) the floor exerts on the ball?
steel ball with a mass of 40.0g is dropped from a height of 2.00 m onto a horizontal steel slab. The ball rebounds to a height of 1.60m. A) Calculate the impulse delivered on the ball during the impact. B) If the ball is in contact with the slab for 2 ms find the average force on the ball during the impact?
A 1.2 kg ball drops vertically onto afloor, hitting with a speed of 20 m/s.It rebounds with an initial speed of 10 m/s. (a) What impulse acts on the ball during thecontact? kg·m/s (b) If the ball is in contact with the floor for 0.020 s, what is the average force exerted on thefloor? N
5. A 0.6 kg ball is dropped with no initial speed from a height of 8 m. The ball bounces off the ground vertically, reaching a height of 7 m. Calculate: (i) The speed of the ball when it hits the ground. (ii) The speed of the ball when it nounces off the ground. (iii) The (magnitude of the) impulse provided by the ground. 6. A 0.2 kg ball hits a bat at 20 m/s and bounces back at 40...
J, A falling 0.1 kg ball has a speed of 7.0 m/s just before it hits the floor and an upward speed of 5 0 ms immediately after it rebounds. The ball is in contact with the floor for 0.01 s. What is the magnitude (in N) of the average force exerted by the floor on the ball?
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...
1. A ball with a mass of m 0.175-kg is dropped from a height of h 2.50 m It rebounds to a height ofh2- 2.00 m (a) Using energy method to find the velocity (magnitude and direction of the ball immedately before hiting the floor? (b) Using energy method to find the velocity (magnitude and drection) of the ball immed iately aftfer hitting the floor? (c) If the collision between the ball and the floor lasts for Δt-0.015 sec, using...
After falling from rest at a height of 34.5 m, a 0.468 kg ball rebounds upward, reaching a height of 23.7 m. If the contact between ball and ground lasted 1.96 ms, what average force was exerted on the ball?
After falling from rest at a height of 32.2 m, a 0.438 kg ball rebounds upward, reaching a height of 20.5 m. If the contact between ball and ground lasted 1.76 ms, what average force was exerted on the ball? (In N)
