A cat is 2 meters away from a 5 meter high box and attempts to jump up on top of it. If the cat jumps at 10 m/s at an angle of 60 degrees off the ground, will he make it?

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.
