A flat car of mass `m_(0)` starts moving to the right due to a constant horizontal force `F.S` and spills on the flat car from a stationary hopper. The rate of loading is constant and equal to `mukg//s`. Find the time dependence of the velocity and the acceleration of the flat car in the process of loading. the friction is negligibly small.

Text Solution

Verified by Experts

The correct Answer is:
`"["(Ft)/(M(1+(rt)/(M))),F/(M(1+(rt)/(M))^(2)"]"`
