Find Part D and E

Given: A bail of mass I kg is released from rest at A. and rolls down a
quarter cirole .until point B. The ball leaves point B with a
horizantal velocity VB and undergoes projectile motion; At peirnt c
the player nits' the ball with å force of 1000 N, 45° above
the harizantal and the point of impoct lasts ť = 0,005 secnds.
Famoring air resistance and assuming the work done by triction
from A to B is -20 J.
Find:o) work dane by greavity on ball
b) Net work done by all farces on
the boll from A-B
