Part A $.$

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

If the upward speed of the hoist increases uniformly from to $1\mathrm{.}5\frac{m}{s}$ to $2\mathrm{.}3\frac{m}{s}$ in $1\mathrm{.}8s,$ determine the average power generated by the motor $M$ during this time. The motor operates with an efficiency of $lon=0\mathrm{.}8$
