Aball is kicked straight up from ground level at a velocity of 13 m/s. find:
a) the maximum height
b) the time at which the ball reaches maximum height
c) the time required for the entire trip
d) the ball's velocity just before it hits the ground upon returning

Which articulations allow for greatest range of motion?

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.

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.
