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 $1\mathrm{.}5\frac{m}{s}$ to $2\mathrm{.}5\frac{m}{s}$ in $1\mathrm{.}5s,$ determine the average power generated by the motor $M$ during this time: The motor operates with an efficiency of $lon=0\mathrm{.}8$

Express your answer to three significant figures and include the appropriate units.

$P_{\text{a}\text{v}\text{g}}=5,9527,kW$
