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.

When you turn on a battery-operated device, an electrical circuit is

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?
