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.

What term do psychologists use to designate our personal awareness of feelings, sensations, and thoughts?

Which of the following is not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?
