What force is needed to give a 4.5 kg bowling ball an acceleration of 9 m/s^2

40.5 N

Explanation:

Newton's second law states that the force applied to an object is directly proportional to the acceleration of the object, following the relationship

where

F is the force applied

m is the mass of the object

a is the acceleration

In this problem, we have

m=4.5 kg is the mass of the bowling ball

is its acceleration

Therefore, the force applied on the ball is

e/c, where e is its total energy
