Inclined Ramp_1

A box of mass m is released from rest at the top of a frictionless ramp, as shown below. Derive an expression for the acceleration of the box in terms of θ and any fundamental constants. If the initial height h is 8 m, what is the box instantaneous speed |𝑣(𝑡)|at the bottom of the ramp? Calculate the time it takes to reach the bottom of the ramp.
