Two inclined frictionless tracks, one gradual and the other steep meet at A from where two stones are allowed to slide down from rest, one on each track. Will the stones reach the bottom at the same time ? Will they reach there with same speed ? Explain. Give \$\teta1 \$ = 30°, \$\teta2 \$ = 60° and h = 10 m, what are the speeds and times taken by the two stones ?
