Question

A 10-g pin ball rolls over a track like the one shown above. If the second hill forms a curvature with a radius of 1.5 m, what is the maximum velocity that the pin ball can roll with over the top of the second hill without flying off? G) 10g=mass 1.5m=radius U) VF=? E)

Answer 1

weight down = mass times centripetal A down
mass cancels, does not matter
g = v^2/R
