Asmall block of mass m is released from rest at point a at the top of a frictionless quarter-circular slide of radius r. it slides down to point b and across a rough horizontal surface. after sliding a distance l to point c, the block encounters a spring of spring constant k, and compresses it a distance d before coming to rest at point p. the surface is rough all the way from point b to point p. derive an expression for the coefficient of kinetic friction between the floor and the block, in terms of relevant system parameters.

If a substance is in the gas phase, which of qualities of the gas will stay constant? a: volume b: mass c: shape d: position of particles

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
