A 0.60 kg rubber ball has a speed of 2.0 m/s at point A and kinetic energy of 6.0 J at point B.
(a) Determine the ball's kinetic energy at A.
J
(b) Determine the total work done on the ball as it moves from A to B.
J

(a) You know the formula for kinetic energy (KE). They tell you M and V. Apply the formula at A.
(b) The wrk done on the ball is the increase in KE from A to B.
