Question

In simple rectilinear motion a 5 kg mass is given at constant acceleration of 3.0 m/s². Find the acting force F.
1. 5 N
2. 15 N
3. 10 N
4. 20 N

Answer 1

Correct Answer - Option 2 : 15 N

CONCEPT:

Force: The interaction which after applying on body changes or try to change the state of rest or state of motion is called force. It is denoted by F

Force (F) = Mass (m) × Acceleration (a)

CALCULATION:

Given that:

Mass (m) = 5 kg

Acceleration (a) = 3 m/s2

Force (F) = Mass (m) × Acceleration (a) = 5 × 3 = 15 N
