A student exerts a 120 N horizontal force on a 25-kg carton of apples, causing it to slide at a constant speed. What is the coefficient of friction between the carton and the ground?

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.
