a smart monkey uses a vine to lower a coconut down from a tree branch $33\mathrm{.}0$m from the ground. the coconuts mass is $1\mathrm{.}44$kg

a$)$ determine the work done on the coconut by gravity

b$)$ calculate the kinetic energy of the coconut when it is lowered at a constant speed of $2\mathrm{.}00$m$/$s down to the ground

c$)$ deterkine the change in potential energy of the coconut when it reaches the ground

d$)$ the vine snaps when the coconut has only been lowered $5\mathrm{.}00$ metres. determine its change in kinetic energy from the point the vine snaps to when it hits the ground
