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.
