Step 1

First, let's find the potential energy at point A. The potential energy is given by the formula PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height. At point A, the height is h - SR, so the potential energy at point A is PE_A = Show more…

Use conservation of energy to find the velocity at point C. The block was able to reach point C. What is the work done by gravity? Find the work done by gravity from point A to B. m = 0.5 kg, R = 0.25 m. A small block changes height from h - SR to h = 0 at B. Take + direction downward.
