Meriam, Kraige & Bolton — Kinetics of Systems of Particles: Problem 4_74

4/73 Sand is released from the hopper $H$ with negligible velocity and then falls a distance $h$ to the conveyor belt. The mass flow rate from the hopper is $m'$. Develop an expression for the steady-state belt speed $v$ for the case $h = 0$. Assume that the sand quickly acquires the belt velocity with no rebound, and neglect friction at the pulleys $A$ and $B$. 4/74 Repeat the previous problem, but now let $h \neq 0$. Then evaluate your expression for the conditions $h = 2\text{ m}$, $L = 10\text{ m}$, and $\theta = 25^\circ$.
