Question

Tarzan (mT 90.0 kg) swings down from the cliff and has a speed of 11.5 m/s just before he impacts Jane (mj 55.0 kg). Answer the two questions below, using three significant digits. Part A: Suppose the Tarzan is able to grab Jane, and the two of them swing together as a single unit. What is the speed of the pair (Vp)? Number V- m/s Part B: Suppose that Tarzan isn't fast enough to grab Jane secure, and instead, he bumps her, sending her forward. He has a forward speed of 2.55 m/s. What is Jane's forward speed (vj)? Number VJ m s

Explanation / Answer

Using conservation of momentum

90*11.5+0= (90+55)*v

V= 7.138 m/s

------------

Again using conservation of momentum

90*11.5+0= 90*2.55+ 55*v'

v'= 14.645 m/s

---------

Comment in case any doubt.. good luck
