Sand is falling on a flat car being pulled with constant speed. The rate of mass falling on the cart is constant. Then the horizontal component of force exerted by the falling sand on the cart (sand particles sticks to the cart)

A cart moves with a constant speed along a horizontal circular path. From the cart, a particle is thrown up vertically with respect to the cart.

A motor drives a belt at a constant velocity of v m*s^(-1) . If m kg of sand fall on the belt per second ,what is the rate of work done by the force exerted by the belt on the sand ?

A cart is set rolling across a level table , at the same speed on every trial. If it runs into a patch of sand, the cart exerts on the sand an average horizontal force of 6N and travels a distance of 6 cm through the sand as it comes to a stop. If instead the cart runs inton a patch of gravel on which the cart exerts an average horizontal force of 9 N how far into the gravel will the cart roll before stopping?

A cart is moving horizontally along a straight line with constant speed 30 m/s. A projectile is to be fired from the moving cart in such a way that it will return to the cart after the cart has moved 120m. At what speed (relative to the cart, in m/s) must the projectile be fired ? (Take g=10m//s^2 )
