Problem $14\mathrm{.}59$

$9$ of $10$

The material hoist and the load have a total mass of $900kg$ and the counterweight $C$ has a mass of $250kg($Figure $1)$

Part A

If the upward speed of the hoist increases uniformly from to $15\frac{m}{s}$ to $25\frac{m}{s}$ in $1\mathrm{.}5s,$ determine the average power generated by the motor $M$ during this time. The motor operates with an efficiency of $lon=08$
