A high-jumper clears the bar and has a downward velocity of 11 .6 ms just before landing on an air mattress and bouncing up at 3.12] W5- The mass ofthe highjumper is ?1 kg. 1Ii'iu'hat is the magnitude of the impulse, in his, that the air mattress exerts on her? Assume that upward is the positive direction. Please round your answer to the nearest whole number {integer}. A 7.8-kg bowling ball strikes a 1.03-kg pin at rest head-on. Before the collision, the velocity of the ball is 12.1 m/s. After the collision, the velocity of the ball is 6.4 m/s. What is the velocity of the pin after the collision? Please round your answer to the nearest whole number (integer).A M171 = 7.3-kg ball ( ball 1) moving at V1; = 8.5 m/s to the right makes a head-on elastic collision with a //12= 15.0-kg ball (ball 2) moving at V2; = 4.1 m/s to the left. What is the magnitude (take the absolute value) of the final speed, Vy, of the ball 1 (i.e., mass /171 ball)? Please round your answer to one decimal place
