Question

The figure shown a long cart moving on a
smooth horizontal surface due to an external
constant force of magnitude F. Initial mass of
the cart is Mo and its initial velocity is zero. At
t = 0, sand starts falling from a stationary
hopper onto the cart at constant rate ukgs-1
and sticks to the cart. After time to the sand
starts leaking from the bottom at the same
constant rare u kgs 1. Eventually at time t =
2to, the sand stops falling from the hopper on
to the cart and force F also stops acting. based on above information answer the following
in the same model of the above question if the cart is to be moved with constant velocity u then the power supplied by external agent applying that force is​
