Here we solve for the velocity of a block as it's sliding up a circular hill using energy methods 1) Find work done by external forces (it's 0). 2) Notice there is negligible rotation so the kinetic energy is just 0.5 m (v2^2 - v1^2). 3) Find h1 and h2 using the geometry after creating a reference axis. 4) Solve the algebra :)
