It's actually a study review he gave us for finals next week.
1. Tarzan swings on a 30.m vine initially inclinded at a 37º angle with the vertical. What is his speed at the bottom of the swing if he:
a. starts from rest
b. pushes off with a speed of 4m/s
(I dont have his mass, and I have no idea what to do with the 37º)
2. A window washer is on one of those scaffolds with a rope on each end. The scaffold=205N and is 3m long.
What is the force each rope exerts when a 675N worker stands 1m from one end?
Thanks for any help. (remember I just need equations...book seems to not want to say)
