A 20.0-kg box initially at rest is released from the top of an incline that is 10.0 m long and makes an angle: physics Assignment, UKM, Malaysia

2. A 20.0-kg box initially at rest is released from the top of an incline that is 10.0 m long and makes an angle of 50° to the horizontal. The incline is adhesive and thus impedes the motion of the box. If the kinetic friction coefficient of the inclined surface is «4 = 0.10, determine

(a) the acceleration of the box.
(b) the box’s speed as it reaches the bottom of the incline
(c) the box’s speed as it reaches the bottom of the incline if the incline is frictionless. Explain the difference in your finding as compared to your answer in 2(b).
