Problem

A stunt motorcyclist rides horizontally off a cliff that is level with the take-off ramp. The platform on the far side is

12\,\text{m}

away and

3.0\,\text{m}

lower than the launch point. Neglecting air resistance, what is the minimum horizontal speed the cyclist must have to just reach the platform? (a)

12\,\text{m}\,\text{s}^{-1}

(b)

10.8\,\text{m}\,\text{s}^{-1}

(c)

15\,\text{m}\,\text{s}^{-1}

(d)

18\,\text{m}\,\text{s}^{-1}
