A ball of mass m slides down a frictionless ramp from an initial height h1 = 10 m with respect to the ground. The ramp exhibits a curvature near the bottom such that the
ball is launched from the end of the ramp at a height h2 = 1 m above ground level and at
an inclination angle of θ = 40◦ with respect to the horizontal (see figure). Find the total
distance ∆x that the ball lands as measured from the end of the ramp, assuming that the
ball lands at ground level. Ignore air resistance, and treat the ball as a point source.
