can some1 show me the formula to find the time? for some reason, i can't find it in my textbook.

With no friction, the weight component down the ramp is Mg sin A, where g is the angle. That equals M a, so the acceleration is a = g sin A

The time T required is given by

(1/2)a T^2 = (1/2)g sin A

Solve for T
