A solid ball with mass m = 2 kg rolls down an inclined plane. The plane has a length L = 5 m, and an angle with respect to the horizontal of 20 degrees. Taking into account the moment of inertia of the ball, what is the speed of the ball when it gets down to the bottom of the plane if it started up at the top at rest.
*Note - I'm really bad at algebra, so it helps if you show the steps if the algebra. That's my weakest point when it comes to physics, is solving the algebra problem.
