A volleyball with a mass of 0.272 kg approaches a player horizontally with a speed of 17.0 m/s. The player strikes the ball with her hand, which causes the ball to move in the opposite direction with a speed of 21.3 m/s.   (a) What magnitude of impulse (in kg · m/s) is delivered to the ball by the player?   If the player's hand 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 hand by the ball?  N

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 At = 0.471 ms, and the radar gun clocks the speed of the ball as Ub = 146 mph after it comes off the club. The golf ball has a mass of mb = 45.9 g. What is the magnitude of the impulse imparted to the ball by the club? magnitude of the impulse: 67.014 Incorrect What is the magnitude of the average force of contact between the club and the ball? magnitude of the average force of contact: 142280.25 Incorrect kg. m S N

A 0.280 kg volleyball approaches a player horizontally with a speed of 15.0 m/s. The player strikes the ball with her fist and causes the ball to move in the opposite direction with a speed of 22.0 m/s. a) what impulse is delivered to the ball by the player? b) if the players fist is in contact with the ball for 0.600s, find the magnitude of the average force exerted on the players' fist.

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?

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 stone is dropped from a height of h1 = 3.55 m above the ground. After it bounces, it only makes it to a height h2 = 2.37 m above the ground. The stone has mass m = 0.148 kg.  a) What is the magnitude of the impulse I, in kilogram meters per second, the stone experienced during the bounce?   b)  If the stone was in contact with the ground for t = 0.153 s, what was the magnitude of the constant force F acting on it, in newtons?   c) How much energy, in joules, did the stone transfer to the environment during the bounce?

A rubber ball of mass 29.5 g is dropped from a height of 1.95 m onto a floor. The velocity of the ball is reversed by the collision with the floor, and the ball rebounds to a height of 1.55 m. What impulse was applied to the ball during the collision?

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 0.261-kg volleyball approaches a player horizontally with a speed of 17.0 m/s. The player strikes the ball with her fist and causes the ball to move in the opposite direction with a speed of 21.8 m/s. (a) What impulse is delivered to the ball by the player? (Take the direction of final velocity to be the positive direction. Indicate the direction with the sign of your answer.) kg - m/s (b) If the player's fist is in contact with the ball for 0.0600 s, find the magnitude of the average force exerted on the player's fist.
