Q. An empty sled of 25kg slides down a muddy hill with a constant speed of 2.4m/s. the slope of the hill is inclined at the angle of 15 degrees. Calculate friction force as it slides down the slope.

Q. An 86 Kg person stands on a uniform ladder 4m long, that weighs 70N. The floor is rough; hence, it exerts both a normal force, and a frictional force, on ladder. The wall, on the other hand, is frictionless; it exerts only the normal force. What are the forces?
