Can anybody me with this? ? (picture included.)

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.

Which articulations allow for greatest range of motion?

Which atomic model was proposed as a result of j. j. thomson’s work?
