A ball of mass .62 kg has an initial velocity of 7 m/s and moves at an angle of 32° above the +x-direction. The ball hits a vertical wall and bounces off so that it is moving 32° above the -x-direction with the same speed. (a) What is the magnitude of the impulse delivered by the wall? Number (b) What is the direction of the impulse delivered by the wall? OO O O +x-direction -x-direction +y-direction -y-direction None of the above

A child bounces a superball on the sidewalk. The linear impulse delivered bythe sidewalk is 3.09 N· s during the 0.351 ms of contact. What is the magnitude of theaverage force exerted on the ball by the sidewalk.

A baseball player pitches a fastball toward home plate at a speed of 41.0 m/s. The batter swings, connects with the ball of mass 335 g, and hits it so that the ball leaves the bat with a speed of 37.0 m/s. Assume that the ball is moving horizontally just before and just after the collision with the bat. (a) What is the impulse delivered to the ball by the bat? Enter a positive value if the impulse is in the direction the bat pushes the ball and  enter a negative value if the impulse is in the opposite direction the bat pushes the ball. ____kg·m/s  (b) If the bat and ball are in contact for 3.00 ms, what is the magnitude of the average force exerted on the ball by the bat? ____kN

A 0.279-kg volleyball approaches a player horizontally with a speed of 12.4 m/s. The player strikes the ball with her fist and causes the ball to move in the opposite direction with a speed of 21.1 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.) (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.

irai, a 50 kg figure skater, lands on the ice her feet after landing the triple axel and immediately jumps up again to perform a double toe-loop. The instant before her skates first touch the ice after the triple axel, her vertical velocity is 3 m/s downward. Her velocity is 2 m/s upward when her skates leave the ice for the second jump, 0.8 s later. (a) What is the vertical impulse exerted on Mirai during the 0.8 s she is in contact with the ice between the two jumps? (b) What is the average net vertical force exerted on Mirai during this 0.8 s? (c) What is the average reaction force exerted upward by the ice on Mirai during the 0.8 s?
