14)A person whose mass is ?=72.0 kg steps on a mechanical bathroom scale placed on an inclined plane that makes the angle ?=28.7∘ with the horizontal. What is the reading on the scale? reading_______kg 17) A 3.980 kg block of wood rests on a steel desk. The coefficient of static friction between the block and the desk is ?s=0.555 and the coefficient of kinetic friction is ?k=0.205. At time ?=0, a force ?=13.3 N is applied horizontally to the block....
3. A person with a mass, m 100 kg is standing on a scale calibrated in Newtons inside a completely enclosed tank with negligible mass. The tank is placed on a fixed, frictionless inclined plane. A force, F 290 N is directed up the incline as shown. The tank is released from rest and begins to accelerate. Inside the enclosed tank, the person on the scale has no knowledge of the inclined plane or the force, F 30° e Wlis...
