A uniform solid ball rolls down a slope. If the ball has a diameter of .5m and a mass of .1 kg find the following:
The equation which describes the velocity of the ball at any time, given that it starts from rest.
I've tried using energy equations, thus: 1/2 Iw^2+1/2Mv^2+mgh = constant (Kf +Uf = Ki + Ui) but that doesn't have "t" as a variable. I have also tried θ-θi=1/2(ωi+ω)t. But that didn't end up taking the radius or mass into consideration.
The Attempt at a Solution
More or less stated in the relevant equations. This is due in a few hours, so anything is much appreciated. Thank you in advance!
