(b)

To find the frictional force offered by the ground

$v=u+a t$

$v=0$

$0=8-\mu g(10)$

$\mu=\frac{8}{100}=0.08$

To move the body with constant velocity on this surface, internal force applied should be equal to friction force $F=\mu m g$

$=(0.08)(1)(10)=0.8\,N$

An object of mass $1 \,kg$ moving on a horizontal surface with initial velocity $8 \,m / s$ comes to rest after $10 \,s$. If one wants to keep the object moving on the same surface with velocity $8 \,m / s$ the force required is ...... $N$
