A particle is in uniform circular motion. Assume a standard rtz coordinate system. If you deconstruct the net force acting on the particle along each of these axes (r (radial), t (tangential), and z (perpendicular to the plane of motion), how many non-zero force components exist?

a) One
b) Two
c) Three
d) Zero - There is no net force on a particle in uniform circular motion

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

How will the system respond to a temperature increase?

A0.580-kg rock is tied to the end of a string and is swung in a circle with a radius of 0.500 meters. the velocity of the rock is 4.50 m/s. what is the centripetal force acting on the rock? 15.5 n 5.22 n 69.8 n 23.5 n
