Question

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

Answer 1

C) 4.0 m/s²

Step-by-step 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.
