Matthew throws a ball straight up into the air. it rises for a period of time and then begins to drop. at which points in the ball’s journey will gravity be the greatest force acting on the ball?

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.
