A clerk moves a box of cans down an aisle by pulling horizontally on a strap attached to the box. The clerk pulls with a force of 185.0 N. The box has a mass of 35.0 kg and the coefficient of kinetic friction between the box and the floor is 0.45. find the acceleration of the box. in m/s^2

The slotted link is pinned at o, and as a result of rotation it drives the peg p along the horizontal guide. compute the magnitude of the velocity and acceleration of p along the horizontal guide. compute the magnitudes of the velocity and acceleration of p as a function of θ if θ=(3t) rad, where t is measured in seconds.

If the speed of a particle triples ,by what factor does its kinetic energy increase?

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude
