While playing volleyball, a player sees the ball coming toward them with a velocity of 10 m/s. They hit the ball, and the ball rebounds at an angle of 30owith a velocity of 15 m/s. Find the impulse and find the average force applied to the ball during impact if the mass of the ball is 1 kg and the time of the impulse was 2 ms.

When spiking a volleyball, a player changes the velocity of the ball from 5.1 m/s to -23.2 m/s along a certain direction. If the impulse delivered to the ball by the player is -9.1 kg · m/s, what is the mass of the volleyball?
A 0.45 kg volleyball is traveling toward you with a horizontal velocity of 3.6 m/s over the net. You jump up and hit it back with a horizontal velocity of 7.0 m/s. If the contact time is 0.400s, what is the impulse and average force on the ball?
Ed Example Problem A soccer player hits a ball (mass m = 440 g) coming at him with a velocity of 20 m/s. After it was hit, the ball travels in the opposite direction with a velocity of 30 m/s. (a) What impulse acts on the ball while it is in contact with the foot? (b) The impact time is 0.1s. What is force the acting on the ball? 28
A 0.275-kg volleyball approaches a player horizontally with a speed of 16.6 m/s. The player strikes the ball with her fist and causes the ball to move in the opposite direction with a speed of 22.4 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...
A 0.277-kg volleyball approaches a player horizontally with a speed of 16.8 m/s. The player strikes the ball with her fist and causes the ball to move in the opposite direction with a speed of 22.6 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...
A 0.261-kg volleyball approaches a player horizontally with a speed of 14.2 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...
A member of the volleyball team spikes the ball. During this process, she changes the velocity of the ball from 3.80 m/s to −22.5 m/s along a certain direction. If the impulse she delivers to the ball is −7.15 kg · m/s, determine the mass of the volleyball.
A 0.231-kg volleyball approaches a player horizontally with a speed of 12.2 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? kg·m/s (b) If the player's fist is in contact with the ball for 0.060 0 s, find the magnitude of the average force exerted on the player's fist.
