A 5.30 kg steel ball is dropped onto a copper plate from a height of 10.0 m. If the ball leaves a dent 3.25 mm deep, what is the average force exerted by the plate on the ball during the impact? N

A 20 g glob of clay traveling east at 3.0 m/s collides with 30 g glob of clay traveling north at 2.0 m/s.  Determine the speed of travel of the resulting 50 g glob of clay.

n with a force of 100 N, what is the most weight that the large piston can support? t ? GMA MINT 49. How many watts of power do you expend when you exert a force of 50 N that moves a crate 8 m in a time interval of 4 s? 50. Emily holds a banana of mass m over the edge of a bridge of height h. She drops the banana and it falls to the river below. Use conservation of energy to show that the speed of the banana just before hitting the water is v = √2gh. daid vil a. Speed b. KE c. PE 53. The roller coaster ride starts from rest at point A. Rank these quantities from greatest to least point: UJ

A 0.430-kg blue bead slides on a frictionless, curved wire, starting from rest at point O in the figure below, where h = 1.50 m. At point O, the blue bead collides elastically with a 0.640-kg green bead at rest. Find the maximum height the green bead rises as it moves up the wire.

The 1-kg ball is thrown at the suspended 10-kg block with a velocity of 4 m/s. If the coefficient of restitution between the ball and the block is e=0.8, determine the maximum height h to which the block will swing before it momentarily stops. 4 m/s В h A

A car's bumper is designed to withstand a 4.32 km/h (1.2-m/s) collision with an immovable object without damage to the body of the car. The bumper cushions the shock by absorbing the force over a distance. Calculate the magnitude of the average force on a bumper that collapses 0.270 m while bringing a 820 kg car to rest from an initial speed of 1.2 m/s.  N

A rubber ball is dropped and bounces vertically from a horizontal concrete floor. If the ball has a speed of 3.2 m/s just before striking the floor and a speed of 2.4 m/s just after bouncing, what is the average force of the floor on the ball? Assume the ball is in contact with the floor for 0.15 s and the mass of the ball is 0.14 kg. N
