Question

. An object has a mass of 13.5 kilograms. What force is required to accelerate it to a rate of 9.5 m/s2? A. 128.25 N B. 173.75 N C. 81.00 N D. 132.30 N

Answer 1

It will require 128.25 newtons to accelerate it. use newtons 2nd law (F=ma)

Answer 2

Option A is correct

The force is required is 128.25 N

Explanation:

Given: mass of an object (m) = 13.5 kilogram and acceleration (a) = 9.5
`m/s^2`

To find the force required;

According to Newton's second Law:

Net Force= mass times acceleration i.e F = ma

Using second law, and substitute the given values above we have;

`F = 13.5 * 9.5 =128.25 kg m/s^2`

We know that 1 Newton =
`kg m/s^2`

therefore; the force is required is, 128.25 N
