Answer:-
Given:
Mass of an object = 6 kg.
Initial Velocity of the object (u) = 3 m/s
Final Velocity of the object (v) = 13 m/s.
Time taken = 5 s.
Acceleration produced = (v - u)/t.
→ a = (13 - 3)/5
→ a = (10)/5
→ a = 2 m/s².
We know that,
Force applied = mass of the object* Acceleration of the object.
→ F = 6 kg * 2 m/s²
→ F = 12 kg m/s²
→ F = 12 N.
Therefore, the force applied is 12 N.

Given:-
- Mass (m) of the particle = 6 kg
- Initial velocity (u) = 3 m/s
- Final velocity (v) = 13 m/s
- Time taken (t) = 5 seconds
To Find: Magnitude of the force exerted in the particle.
We know,
- F = ma &
- a = (v - u)/t
∴ F = m[(v - u)/t]
where,
- F = Force,
- a = Acceleration,
- v, u = Final and initial velocities respectively,
- t = Time taken.
∴ F = (6 kg)[(13 m/s - 3 m/s)/5s]
→ F = (6 kg)(2 m/s²)
→ F = 12 kg m/s²
→ F = 12 N
∴ Force exerted on the particle was 12 Newtons.
