Tarzan $($mT$=83\mathrm{.}4$kgmT$=83\mathrm{.}4$kg$)$ swings down from a cliff and has a speed of$14\mathrm{.}9$m$/$s$14\mathrm{.}9$m$/$s just before he impacts Jane $($mJ$=53\mathrm{.}5$kgmJ$=53\mathrm{.}5$kg$).$

Part A $-$ Suppose that Tarzan is able to grab Jane, and the two of them swing together as a single unit. What is the speed, vpvp$,$ of the pair?

Part B $-$ Suppose that Tarzan is unable to grab Jane securely$,$ and she bounces away from him. After the collision, he has a forward speed of $4\mathrm{.}60$m$/$s$4\mathrm{.}60$m$/$s$.$ What is Jane's forward speed, vJvJ$?$

Part C $-$ What what was the impulse force, FimpFimp, in Part B acting on Jane if the collision time was $0\mathrm{.}170$s$0\mathrm{.}170$s$.$
