Physics, ball and diaper

Good evening! I will appriciate any help! :-)

A soft ball weighing m1 = 19 g fell free-fall when hit by a weight of m0 = 0.54 g at a velocity of v0 = 170 m · s-1 fired from the air rifle. After the diabolic hit in the ball, the ball bent in the center of the ball.
a) Determine the size and speed direction of the ball immediately after the hit if the diaper has come vertically from the rear.
b) Determine the magnitude and direction of the w ball speed immediately after the hit if the diaper has come from the horizontal direction.
