1.Sand from a stationary hopper falls on a mov-
ing conveyor belt at the rate of 4 kg/s, as
shown in the figure. The belt is supported by
frictionless rollers and moves at 1.07 m/s un-
der the action of a horizontal external force
supplied by the motor that drives the belt.
Find the sand’s rate of change of momen-
tum in the horizontal direction. Answer in
units of N.
2. i know the rate of change of momentum is equal to the force but i need help figuring out that i really just need help getting started
