A block lies on a smooth plane tilted at an angle è = 28.5° to the horizontal. Ignore friction.



(a) Determine the acceleration of the block as it slides down the plane.
1 m/s2
(b) If the block starts from rest 9.40 m up the plane from its base, what will be the block's speed when it reaches the bottom of the incline?
2 m/s
