A soccer ball with a mass of 0.45 kg has a velocity of 2.0 m/s to the east. It experiences a sudden kick lasting 0.2 s, causing it to change both its speed and direction. Immediately after the kick, the ball has a velocity of 3.8 m/s to the north. What is the magnitude (in kg m/s) of the impulse that acted on the ball?

A hockey puck (mass 6.00 kg), initially moving in a straight line with a speed of 1.8 m/s is hit with a hockey stick toward the goal. After it is struck, it moves with a speed of 4.4 m/s at an angle of 77 degrees with respect to its initial direction. What is the magnitude of the impulse (in Newton- seconds) that the hockey stick exerted on the puck?

In the overhead view of the figure, a 410 g ball with a speed v of 3.2 m/s strikes a wall at an angle e of 31° and then rebounds with the same speed and angle. It is in contact with the wall for 5.2 ms. In unit-vector notation, what are (a) the impulse on the ball from the wall and (b) the average force on the wall from the ball? (a) Number i i+ j Units (b) Number i i+ i j Units >

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 0.730 m. What impulse was given to the ball by the floor? magnitude    kg · m/s

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 0.8 kg block is moving horizontally to the right with a speed of 6 m/s when it strikes a vertical wall. After the collision, the block is moving to the left with a speed of 2 m/s. What is the magnitude of the impulse on the block

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 hockey player strikes a puck that is initially at rest. The force exerted by the stick on the puck is 967 N, and the stick is in contact with the puck for 4.2 ms (0.0042 s).  how do you find the impulse imparted by the stick to the puck. kg · m/sand , What is the speed of the puck  just after it leaves the hockey stick? mass of puck is 1.65kg m/s

Two rams are fighting and run straight at each other. Ram 1 has m1 = 115 kg and an initial velocity v1 = 9 m/s. Ram 2 has m2 = 127 kg and an initial velocity v2 = -7 m/s. When they collide, they lock horns.  What impulse did Ram 2 deliver to Ram 1?
