15. During the collision, which ball experiences a greater acceleration? a. The bowling ball b. The ping-pong ball c. They experience the same acceleration d. Impossible to determine?​

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

i don't know that i agree with that but what's the question ?

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)

neg x, pos y
