posted by .

1. a little spider monkey named flo has stolen a bunch of bananas from her older brother Charley and is now running away frm him with the bananas in hand. She sees salvation in a long vine and grabs the bottom, hoping to swing away
a) if she has a mass of 5.3kg and the bananas with a mass of 0.5 kg reaches a height of 1.2 m before slowing to a stop and swinging back down, how fast was she running when she grabbed the vine?
b) As she swings back down charley (whose mass is 5.9kg) is standing just at the bottom of the swing.. He grabs her and swings her up together. What height will the two monkeys and the coveted banana reach?
c) As a result of their fighting they happen to drop the bananas just as the vine pendulum reaches this new height. How fast will the two monkeys be moving when they let go off the vine at the bottom again?
