Acceleration Down an Inclined Plane Problem

[nycjay222]

The block shown in figure below lies on a smooth plane tilted at an angle theta = 23.7o to the horizontal.

A) Determine the acceleration of the block as it slides down the plane. Ignore friction.

B) If the block starts from rest x = 9.87 m up the plane from its base, what will be the block's speed when it reaches the bottom of the incline?
