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.
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?
2) A 2 kg ball is dropped and hits the ground at 10 m/s. It rebounds with 80% of its Energy. Calculate the impulse. If the ball is in contact with the ground for.005 sec, find the average force exerted on the ball.
A billiard ball strikes and rebounds from the cushion of a pool table perpendicularly. The mass of the ball is 0.38 kg. The ball approaches the cushion with a velocity of +2.50 m/s and rebounds with a velocity of -1.80 m/s. The ball remains in contact with the cushion for a time of 3.00 × 10-3 s. What is the average net force (magnitude and direction) exerted on the ball by the cushion? F =...... (number) ....... the tolerance is...
A steel ball with mass 41.0 g is dropped from a height of 1.95 monto a horizontal steel slab. The ball rebounds to a height of 1.64 m . A. Calculate the impulse delivered to the ball during impact. B. If the ball is in contact with the slab for a time of 2.10 ms , find the average force on the ball during impact.
After falling from rest from a height of 30m a 0.50kg ball rebounds upward, reaching a height of 20m. If the contact between ball nd ground lasted 2.0ms what average force was exerted on the ball?
A ball is dropped from a height of 2.50 m and rebounds to a height of 2.10 m . Approximately how many rebounds will the ball make before losing 90% of its energy? Express your answer as an integer.
