An object of mass M = 924 g is pushed at a constant speed up a frictionless inclined surface which forms an angle č = 50 degrees with the horizontal as shown in the figure below. What is the magnitude of the force that is exerted by the inclined surface on the object? There is...

physics
A box of textbooks of mass 24.8 rests on a loading ramp that makes an angle with the horizontal. The coefficient of kinetic friction is 0.25 and the coefficient of static friction is 0.35. At this angle, how fast will the box be moving after it has slid a distance 4.9 along ...
