Consider an object on an inclined plane:

A+B A 5.0 kg object rests on an inclined plane that makes an angle of 26o with the horizontal. A) What are the components of gravity parallel and perpendicular to the plane?B) Were the block to slide with no friction down the plane, what would be its acceleration? 5.0 kg 26o

C A 5.0 kg object rests on an inclined plane that makes an angle of 26o with the horizontal. C) What force would make the block slide up the plane with an acceleration of 2.4 m/s/s? (assume no friction) 5.0 kg 26o

D A 5.0 kg object rests on an inclined plane that makes an angle of 26o with the horizontal. D) Suppose Red Elk exerts a force of 31 N down the plane, and the object accelerates at 6.8 m/s/s down the ramp, what other force must be acting along the plane? 5.0 kg 26o

E A 5.0 kg object rests on an inclined plane that makes an angle of 26o with the horizontal. E) The block is given a push of 2.1 m/s up the ramp, and comes to a halt after going .42 m up the ramp. What force must be acting along the plane? 5.0 kg 26o
