Question

A skier plans to ski a smooth fixed hemisphere of radius r. He starts from rest from a curved smooth surface of height (R/4). The angle theta at which he leaves the hemisphere is

Arun · Accepted Answer

∆h=R/4+R(1–cosθ)½ mv^2 =mg∆h= mgR/4 {1+4(1–cosθ)}mv^2/R = mg (5 − 4 cos θ) /2mgcosθ–N= mv^2/ Rmgcosθ= mg(5−4cosθ)/ 2cosθ = 5/6
