ANSWER IS 0.8KN SHOW ALL WORK PLEASE!!!!!
A 100-kg block is pushed up a 30° incline that is 10 m long. If the coefficient of friction between the block and the incline is 0.1, the constant force parallel to the incline that is required to move the block from rest at the bottom of the incline to the top in 3 s is approximately

The 50-10 block rests on the rough surface for which the coefficient of kinetic friction is 0.2. A force F = (40 + s2) lb, where s is in ft, acts on the block in the direction shown. If the spring is originally unstretched (s = 0) and the block is at rest, determine the power developed by the force the instant the block has moved s = 1.5 ft. F. 30° k = 20 lb/ft
