The roller coaster in Figure P$6\mathrm{.}36$ starts with a velocity of $16\mathrm{.}4\frac{m}{s}.$ One of the riders is a small girl of mass $34$ kg $.$ At points $B$ and $C,$ the track is circular with the radii of curvature given in the figure. The heights at points $A,B,$ and $C$ are $h_A=24\mathrm{.}5m,h_B=34\mathrm{.}85m,$ and $h_C=0m.$ You may assume the track is frictionless.
