volleyball is spiked so that it's incoming velocity of 4.53 m/s is changed to an outgoing velocity of -22.2 m/s. The mass of the volleyball is .350 kg. What is the magnitude of the impulse that the player applies to the ball?

A 0.10 kg softball is traveling at 20.00 metres per second to the left. A batter strikes the ball and sends it traveling at 30.00 metres per second to the right. The bat and softball are in contact for 0.25 seconds. At the start of the problem you must state which direction you choose to be positive. What is the initial momentum and direction of the softball? What is the final momentum and direction of the softball? What was the impulse striking on the softball? What was the force of the bat striking the softball?

A basketball of mass 1.25 kg traveling with an initial speed of 8 m/sec bounces off of a backboard and comes back in the opposite direction with a speed of 7 m/sec.  The ball is in contact with the backboard for 0.1 sec.   What is the impulse on the ball?

A girl on a bicycle uses 25 N of force to speed up from 2.0 m/s to 4.0 m/s in 2.0 seconds. The positive direction is the direction of motion. What  is the impulse the bicyclist applies to speed up?

A ball of mass 0.165 kg is dropped from rest from a height of 1.25 m. It rebounds from the floor to reach a height of 0.920 m. What impulse was given to the ball by the floor? kg-m/s

A golf ball m = 0.11 kg strikes a vertical concrete wall elastically with a horizontal velocity of v = 13 m/s.  Write an expression for the magnitude of the impulse I experienced by the ball. If the ball was in contact with the wall for t = .1s, what is the magnitude of the force F the ball experienced in N? If the ball rebounds with only half the velocity it comes in with, what is the magnitude of the impulse in kg m/s? Determine the magnitude of the change in kinetic energy in the above situation. Give your answer in joules.

A ball falls from height of 20.0 m, hits the floor, and rebounds vertically upward to height of 15.0 m. Assume that m ball = 0.385 kg. (a) What is the impulse (in kg. m/s) delivered to the ball by the floor? magnitude x direction 979.1 Assume the only impulse delivered to the ball is from the floor, which equals the change in momentum of the ball. Find the initial and final speeds of the ball using conservation of mechanical energy, and calculate Ap noting that all the motion is in the y-direction. kg. m/s up ✓✓ (b) If the ball is in contact with the floor for 0.0300 seconds, what is the average force (in N) the floor exerts on the ball? magnitude 19.223 x Use the impulse-momentum theorem and the result from part (a) to find the force, given that the contact time interval is 0.0300 s. N up direction ✓✓

A block (mass 4 kg) is initially moving to the left at 10 m/s. After hitting the wall, the ball is moving to the right at 5 m/s. What is the impulse of the net force on the ball during its collision with the wall?

A volleyball is spiked so that its incoming velocity of + 2.50 m/s is changed to an outgoing velocity of - 20.7 m/s. The mass of the volleyball is 0.350 kg. What is the magnitude of the impulse that the player applies to the ball?

A 0.05-kg toy car is initially moving at 1.4 m/s. Since the battery is losing power, the toy car has slowed down to 0.7 m/s. Calculate the impulse of the toy car. Input the numerical value only; do not include the units.
