Question

A net force of 40 N acts on a 20 kg object. Find the object's acceleration.

Answer 1

According to Newton's second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = $\frac{F}{m}$ .

F= 40 N, m= 20 kg.

a = $\frac{40}{20}$ = 2 (m/s²).
