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

Answer:

Option A is correct

The force is required is  128.25 N

Step-by-step 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;

$F = 13.5 \times 9.5 =128.25 kg m/s^2$

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

therefore; the force is required is, 128.25 N

Answer 2

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