Given :-

  • Mass (m) of body = 3 kg
  • Initial (u) velocity = 2 m/s
  • Final (v) velocity = 8 m/s  
  • Time (t) of force applied = 3 s

To find :-

  • The force applied on the object

Answer :-

Using the First equation of motion, we can calculate acceleration (a) as,

\boxed{v = u + at}

\rightarrow a = \frac{v-u}{t}

\rightarrow a = \frac{8-2}{3}

\rightarrow a = \frac{\cancel{6}}{\cancel{3}}

 \Rightarrow a = 2 m/s^{2}

Now, using Newton's second law of motion, we can calculate force (F) as,

\boxed{F = m\times{a}}

 \rightarrow F = 3\times{2}

 \Rightarrow F = 6 N

 \therefore The Force applied on the object was 6 N
