An estimated Forcetime curve for a baseball struck by a bet is shown in the figure below. Let Fma = 19,000 N, ta = 1.5 ms, and ft: = 3 ms. From this curve, X determine the following. I" (N) Fmax 0 ((ms) 0 l'EI [b (D (a) the magnitude of the impulse delivered to the ball (b) the average force exerted on the ball Em A 0.0600 kg ball is traveling horizontally at 24.5 m/s when it is hit by a squash racquet. The ball then moves in the opposite direction, also horizontally, at a speed of 44.0 m/s. Take the initial velocity of the ball to be in the X-direction. (a) What is the impulse delivered to the ball by the squash racquet? (Give the x-component in N ' 5. Indicate the direction with the sign of your answer.) :m-s (b) Some work is done on the system of the ball and some energy appears in the ball as an increase in internal energy during the collision between the ball and the racket. What is the quantity W AE for the ball? (Give your answer in J.) l:lJ int Two blocks are free to slide along the frictionless wooden track shown below. The block of mass m1 = 5.03 kg is released from the position shown, at height h = 5.00 m above the flat part of the track. Protruding from its front end is the north pole of a strong magnet, which repels the north pole of an identical magnet embedded in the back end of the block of mass m2 = 9.30 kg, initially at rest. The two blocks never touch. Calculate the maximum height to which ml rises after the elastic collision. A billiard ball moving at 6.00 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 5.09 m/s at an angle of 32.0 with respect to the original line of motion. Assuming an elastic collision (and ignoring friction and rotational motion), find the struck ball's velocity after the collision. meme: m/e direction :] (with respect to the original line of motion)
