1. The problem statement, all variables and given/known data 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. 2. Relevant equations 1/2mv2 = mgh cos = Y/L h = L ( 1- cos ) 3. The attempt at a solution 1/2(2)(1)^2 = (2)(9.8) h 1 = 19.6h 1/19.6h h = .051 just dont know how to go about gettign resultant angle
yeah i did and got h= 7 tan[tex]\theta[/tex], how would you find the actual angle that what im having difficult with.
