    A small toy car of mass 0.250 kg0.250\,\mathrm{kg} moves uniformly around a horizontal circular track of radius 0.800 m0.800\,\mathrm m. A guide supplies an inward horizontal force of 1.25 N1.25\,\mathrm N. The track is 1.25 m1.25\,\mathrm m above level ground. At P the guide ends and the car leaves horizontally. Ignore drag; use g=10.0 m s−2g=10.0\,\mathrm{m\,s^{-2}}.
