A hockey puck (mass 4.00 kg), initially moving in a straight line with a speed of 1.4 m/s is hit with a hockey stick toward the goal. After it is struck, it moves with a speed of 4.9 m/s at an angle of 141 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?

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 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

A soccer ball with a mass of 0.427 kg approaches a player horizontally with a speed of 14.0 m/s. The player kicks the ball with her foot, which causes the ball to move in the opposite direction with a speed of 22.3 m/s. (a) What magnitude of impulse (in kg · m/s) is delivered to the ball by the player?  kg · m/s   (b)What is the direction of the impulse delivered to the ball by the player? - In the same direction as the ball's initial velocity  - Opposite to the ball's initial velocity       - Perpendicular to the ball's initial velocity  - The magnitude is zero.   (c) If the player's foot is in contact with the ball for 0.0600 s, what is the magnitude of the average force (in N) exerted on the player's foot by the ball?

A force of 90.0 newtons is applied to a cart traveling at 15.0 meters per second. After the force has been applied for 2.00 seconds, it comes to rest. What is the magnitude of the impulse applied to the cart over these 2.00 seconds?

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 professional golfer is examining a video of a practice swing. The high-speed footage shows that his club is in contact with the ball (which was initially at rest on the tee) for only Ar=0.571 ms, and the radar gun clocks the speed of the ball as = 176 mph after it comes off the club. The golf ball has a mass of my = 45.9 g. What is the magnitude of the impulse imparted to the ball by the club? magnitude of the impulse: What is the magnitude of the average force of contact between the club and the ball? magnitude of the average force of contact: kg m N

A 130.0 g ball is moving horizontally to the west at 20.0 m/s when it is hit by a stick. The ball flies off to the 20.0° north of east at 45.0 m/s. What are the magnitude and direction of the impulse that the stick delivers to the ball? 4.90 Ns, 55.4° north of east 10.1 Ns, 76.1° north of east O 3.52 Ns, 34.6° north of east O 3.52 Ns, 55.4° north of east 8.34 Ns, 13.9° north of east O 4.90 Ns, 34.6° north of east 10.1 Ns, 13.9° north of east 8.34 Ns, 76.1° north of east

A volleyball is spiked so that it's incoming velocity of +3.18m/s is changed to an outgoing velocity of -19.8m/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(n) 0.56 kg softball is pitched at a speed of12 m/s. The batter hits it back directly at thepitcher at a speed of 28 m/s. The bat acts onthe ball for 0.017 s.What is the magnitude of the impulse imparted by the bat to the ball?Answer in units of N · s. What is the magnitude of the average forceexerted by the bat on the ball?Answer in units of N.
