This is a "warm$-$up problem" to get you used to using unity conversion ratios and thinking about significant digits in your final answers. A forklift raises a $190\mathrm{.}5$ kg crate $1\mathrm{.}80$ m$.$

$($a$)$ Using unity conversion ratios, calculate the work done by the forklift on the crate, in units of kJ$.$ Show all your work.

$($b$)$ If it takes $12\mathrm{.}3$ seconds to lift the crate, calculate the useful power supplied to the crate in $W,kW,$ and horsepower.

Complete both parts $($A & B$)$ of question and show all work.
