Homework Statement
a 2 kg pendulum of length 7 meters is moving at 1 m/s, calculate how high (h) the pendulum will rise; and the resultant angle.
Homework Equations
1/2mv2 = mgh
cos = Y/L
h = L ( 1- cos )
The Attempt at a Solution
1/2(2)(1)^2 = (2)(9.8) h
1 = 19.6h
1/19.6h
h = .051
just don't know how to go about gettign resultant angle
