Iwill give 60 points and mark them as brainliest if someone can answer these ! (its science, but there's no subject for it)

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 ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

Acar traveling at 22 m/s starts to decelerate steadily. it comes to a complete stop in 15 seconds. what is it’s acceleration?
