The motor $\backslash ($ M $\backslash )$ pulls on the cable with a force of $\backslash (\backslash$mathbf$\{$F$\}\backslash ),$ which has a magnitude that varies as shown on the graph.

Part A

If the $16$ kg crate is originally resting on the floor such that the cable tension is zero at the instant the motor is turned on$,$ determine the speed of the crate when $\backslash ($ t$=6\backslash$mathrm$\{$~s$\}\backslash ).($Hint: First determine the time needed to begin lifting the crate.$)($Figure $1)$
