Question

A force of 15 newtons is applied to both Object A with a mass of 25 kilograms and Object B with a mass of 50 kilograms. What is true about the

acceleration of Object A and Object B?

Answer 1

Acceleration of Object A = 0.6 m/s²

Acceleration of Object B = 0.3 m/s²

Acceleration of Object A is double than the acceleration of Object B.

Step-by-step explanation:

According to the Newton's 2nd law of motion, Acceleration of an object by a net force is directly proportional to the magnitude of that net force and in the direction of that net force and inversely proportional to the mass of the object

Mathematically

F ∝ a

F = ma

Given data:

F = 15 N

m₁ = 25 kg

m₂ = 50 kg

F = m₁a₁

a₁ = F/m₁

a₁ = 15/25

a₁ = 0.6 m/s²

F = m₂a₂

a₂ = F/m₂

a₂ = 15/50

a₂ = 0.3 m/s²

It can be seen that acceleration of Object A is double than the acceleration of Object B.
