Tarzan swings on a 27.0 m long vine initially inclined at an angle of 33.0° with the vertical.
(a) What is his speed at the bottom of the swing if he starts from rest?(b) What is his speed at the bottom of the swing if he pushes off with a speed of 3.00 m/s?

• Physics -

draw the sketch. How high is he initially?

intialPE=finalKE
b) initialPE+ intialKE= finalKE

• Physics -

I drew the sketch, the problem does not tell me how high he is initially, I can find the equation vfinal = the square root of (2gh) but I don't know what h is.

• Physics -

I know this is about 5 years too late, but h would be the length of the vine (21 m)
