Find the value of H

When the box is pushed by the force H then,

 

H - F = mxa           

where, F = Friction force acting in direction opposite to the motion

         a = acceleration = 0 m/s²

        m = mass of the box = 50 Kg.

therefore,

H = F..................(i)

 

Now when the box is pushed by 1.5H then,

 

1.5H - F = mxa₁

 

a₁ = Acceleration = 0.1 m/s²

 

From (i) we get,

1.5H - H = 50x0.1

 

ie, 0.5H = 5

thus, H = 10 N.
