A force of 120 N is applied to an object whose mass is 30 kg. The object's acceleration is:

A) 3600 m/s2.

B) 150 m/s2.

C) 4.0 m/s2.

D) 0.25 m/s2

C) 4.0 m/s²

Explanation:

Given data

Applied force (F) : 120 Newton Mass of the object (m) : 30 kilograms Acceleration of the object (a) : to be determined

We can find the acceleration of the object using Newton's second law of motion.

F = m. a

a = F / m = 120 N / 30 kg = 4.0 m/s²

The acceleration of the object is 4.0 m/s².
