A player kicks a football from ground level with an initial velocity of 27.0 m/s, 30.0° above the horizontal, as shown in the figure. Assume that forces from the air on the ball are negligible.
Find the ball's hang time (time of flight).

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
