Explanation:

Answer:-

The Object was at rest. So, Initial Velocity is Zero.

  • [Initial Velocity]u = 0
  • [Final Velocity]v = 20 m/s
  • [Time]t = 2 seconds
  • Mass = 4kg
  • Force = ?

We know that:-

[tex]\sf{Force = Mass \times \dfrac{(v-u)}{t}}[/tex]

Applying it, we get:-

[tex]\sf{Force = 4 \times \dfrac{(20-0)}{2}}[/tex]

[tex]\sf{Force = 2 \times \dfrac{(20)}{2}}[/tex]

[tex]\sf{Force = 2 \times 10}[/tex]

[tex]\sf{Force = 20 \ N \ (Newton)}[/tex]

Hope it helps :)
