A ball of mass 0.140 kg is dropped from rest from a height of 1.25 m. It rebounds from the floor to reach a height of 0.830 m. What impulse was given to the ball by the floor? magnitude kg. m/s direction --Select-
A ball of mass 0.180 kg is dropped from rest from a height of 1.25 m. It rebounds from the floor to reach a height of 0.785 m. What impulse was given to the ball by the floor? Magnitude
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.
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.
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...
A 190 g ball is dropped from a height of 2.2 m, bounces on a hard floor, and rebounds to a height of 1.1 m. The figure(Figure 1) shows the impulse received from the floor. Part AWhat maximum force does the floor exert on the ball? Express your answer to two significant figures and include the appropriate units.
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?
1 Warm-Up Questions 1 A block of mass m = 3 kg is dropped from the top of a half-pipe (half-circle) of radius R = 2 m starting from rest. The surface of the incline does have friction. If the block comes to rest at half of its initial height, how much work was done by friction? Work: 2 Initially, a ball of mass 0.4 kg is compressed by a spring, with spring constant k = 980 N/m, by a...
