A baseball has mass 0.145 kg. (a) If the velocity of a pitched ball has a magnitude of 45.0 m/s and the batted ball’s velocity is 55.0 m/s in the opposite direction, find the magnitude of the change in momentum of the ball and of the impulse applied to it by the bat. (b) If the ball remains in contact with the bat for 2.00 ms, find the magnitude of the average force applied by the bat.

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 golf ball strikes a hard, smooth floor at an angle of 31.7 ° and, as the drawing shows, rebounds at the same angle. The mass of the ball is 0.0793 kg, and its speed is 38.6 m/s just before and after striking the floor. What is the magnitude of the impulse applied to the golf ball by the floor? (Hint: Note that only the vertical component of the ball's momentum changes during impact with the floor, and ignore the weight of the ball.)

Force of a Baseball Swing. A baseball has mass 0.141 kg. If the velocity of a pitched ball has a magnitude of 46.0 m/sm/s and the batted ball's velocity is 58.0 m/sm/s in the opposite direction, find the magnitude of the change in momentum of the ball and of the impulse applied to it by the bat. If the ball remains in contact with the bat for 1.6 msms , find the magnitude of the average force applied by the bat.

and is in contact with the player's head for 7.1 ms, determine the following. (a) direction of the impulse (in degrees counterclockwise from the +x-axis) delivered to the ball ° counterclockwise from the +x-axis (b) magnitude of the impulse (in kg · m/s) delivered to the ball kg · m/s

A golf ball strikes a hard, smooth floor at an angle of 28.8° and, as the drawing shows, rebounds at the same angle. The mass of the ball is 0.0224 kg, and its speed is 43.8 m/s just before and after striking the floor. What is the'magnitude of the impulse applied to the golf ball by the floor? (Hint: Note that only the vertical component of the ball's momentum changes during impact with the floor, and ignore the weight of the ball.) Number Units

A cruise ship with a mass of 1.43 ✕ 107 kg strikes a pier at a speed of 0.672 m/s. It comes to rest 5.94 m later, damaging the ship, the pier, and the tugboat captain's finances. Calculate the average force (in N) exerted on the pier using the concept of impulse. (Hint: First calculate the time it took to bring the ship to rest. Assume the ship moves in the positive direction. Indicate the direction with the sign of your answer.)

During a baseball game, the collision with the baseball bat changes the velocity of the ball. Assume that the velocity of the ball changed from 3.9 m/s to −24.9 m/s along a certain direction. If the impulse delivered to the ball is −7.9 kg · m/s, determine the mass of the volleyball in kilograms.

Two students are playing paddle ball with a 5 kg spongy ball. If the ball is thrown at the batter with a speed of 5 m/s and bounces off with a speed of 10 m/s. What is the magnitude of the impulse imparted on the ball by the bat?

A soccer ball with a mass of 0.429 kg approaches a player horizontally with a speed of 13.0 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? Opposite to the ball's initial velocity Perpendicular to the ball's initial velocity In the same direction as the ball's initial velocity The magnitude is zero. OOOO (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? N
