Write an expression for the sum of kinetic and potential energies of the box at the initial moment.

Throughout the problem, we denote the mass of the box as m, the angle of the plane as ? = 60?, the length of the plane as d = 0.30 m, the height of the table as H2 = 1.0 m, the initial speed of the box at the top of the plane as v1 = 2.0m/s, and the height from part (b) as H3 = 0.50m. Use the floor as the level of zero gravitational potential energy.

Express your answer in terms of some or all of the variables m, ?, d, ?k, H2, v1, and the acceleration due to gravity g.
