Question

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

Answer 1

Answer: 40.5 N

Step-by-step 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

`F=ma`

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

`a=9 m/s^2` is its acceleration

Therefore, the force applied on the ball is

`F=ma=(4.5 kg)(9 m/s^2)=40.5 N`

Answer 2

F = ma

F = 4.5 * 9

F = 40.5N
