A block lies on a smooth inclined plane tilted at an angle of 35° to the horizontal. (a) Draw the free-body diagram for the block. (b) Determine the block's acceleration as it slides down the inclined plane
(c) If the block started from rest 8.5 m up the incline from its base, determine the block's speed when it reaches the bottom of the incline. (d) How long did it take the block to reach the bottom of the inclined plane?
(a) The block is acted on by the force of gravity directed downward and the normal force due to the inclined plane directed perpendicular to the inclined surface.
(b) 5.6 m/ s2
(c) 9.8 m/s
(d) 1.7 s
