You throw a basketball by exerting a force of 20 newtons. According to Newton's third law, there is another 20 -newton force created in the opposite direction. If there are two equal forces in opposite directions how does the ball accelerate ?

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 a tank filled with water contains a block and the height of the water above point a within the block is 0.8 meter, what is the pressure at point a?
