A soccer ball player bounces the ball off her head, changing the velocity of the ball. She changes the x-component of the velocity of the ball from vix = 8.4 m/s to Vx = 3.8 m/s and the y-component from vy = -1.8 m/s to Vy = 3.8 m/s. If the ball has a mass of 0.43 kg 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/s4.

Before he can move, a tackler, running at a velocity of +3.3 m/s, grabs and holds onto him so that they move off together with a velocity of +1.7 m/s. If the mass of the tackler is 105 kg, determine the mass of the receiver in kilograms. Assume momentum is conserved. kg 5. [-/1 Points] DETAILS SERCPWA11 6.WA.014. MY NOTES PRACTICE ANO Two ice skaters stand facing each other at rest on a frozen pond. They push off against one another and the 48 kg skater acquires a speed of 0.74 m/s. If the other skater acquires a speed of 0.83 m/s, what is her mass in kilograms? kgA truck with a mass of 1520 kg and moving with a speed of 1 5.0 m/s rear-ends a 629 kg car stopped r is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. Fi the collision in meters per second. car m/s Vtruck = m/sAn angry rhino with a mass of 2500 kg charges directly toward you with a speed of 4.00 m/s. Before you start running, as a distraction, you throw a 0.180 kg rubber ball directly at the rhino with a speed of 7.27 m/s. Determine the speed of the ball (in m/s) after it bounces back elastically toward you. m/s
