A ball is kicked from the top of one building towards another building that is 15.24 m away. The initial velocity of the ball is 6.1 m/s 40° above the horizontal. How far above or below its original
level will the ball strike the opposite wall?

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.
