Using energy methods, determine (a) the kinetic energy of the ball at the top of its flight and (b) its speed when it is 2.0 m below the window. Does the answer to (b) depend on either (c) the mass of the ball or (d) the initial angle?

A bicyclist starting from rest applies a force of F = 239 N to ride his bicycle across flat ground for a distance of d = 210 m before encountering a hill making an angle of θ = 17 degrees with respect to the horizontal.
