Question

Suppose that a constant force is applied to an object. Newton's Second Law of Motion states that the acceleration of the object varies inversely with its mass. A constant force acting upon an object with mass

2 kg
produces an acceleration of
15 /ms2
. The acceleration of another object produced by the same force is
6 /ms2
. What is the mass of this object

Answer 1

Force = Mass × Acceleration;

First Force: 15×2 =30 kg ms^2

So, 30= 6 × ?

30 / 6 = 5 kg

Answer 2

Mass of the object = 5 kg

Explanation:

We have force is the product of mass and acceleration.

Force = Mass x Acceleration

A constant force acting upon an object with mass 2 kg produces an acceleration of 15 /ms²

That is

F = 2 x 15 = 30 N

The acceleration of another object produced by the same force is 6 m/s², we need to find mass of the object.

We have force = 30 N and acceleration = 6 m/s²

30 = m x 6

m = 5 kg

Mass of the object = 5 kg
