Question

A force of 60 N is acted on a body of mass 1.5 kg at rest, the acceleration of the body is

(A) 4 ms−2 (B) 40 ms−2 (C) 5 cms−2 (D) 40 cms−2

Answer 1

Force = Mass * Acceleration
Therefore, Acceleration = Force / Mass = 60/1.5 = 40 ms-2 (B)

Answer 2

The acceleration of the body is (B) 40 m/s².

Given - Force and mass

Find - Acceleration

Solution - Force, mass and acceleration are related to each other as follows -

Force = mass*acceleration

60 = 1.5*acceleration

Acceleration = 60/1.5

Performing division

Acceleration = 40 m/s²

Hence, the acceleration of the body is (B) 40 m/s².
