Physics

As shown in the figure (Figure 1) , a superball withmass m equal to 50 grams is dropped from a height ofhi=1.5m . It collides with a table, then bounces up to aheight ofÂ Â hf=1.0m . The duration of thecollision (the time during which the superball is in contact withthe table) is tc=15ms . In this problem, take the positivey direction to be upward, and use g=9.8m/s2 forthe magnitude of the acceleration due to gravity. Neglect airresistance.
Find the y component of the momentum,pbefore,y, of the ball immediately before thecollision.
Find the y component of the momentum of the ballimmediately after the collision, that is, just as it is leaving thetable.
Find Jy, the y component of theimpulse imparted to the ball during the collision.
Find the y component of the time-averaged forceFavg,y, in newtons, that the table exerts on theball.
Find Kafter?Kbefore, the change in the kineticenergy of the ball during the collision, in joules.
