1. Elizabeth throws a coin vertically into the air. At its highest point, it is 3.1 meters above the ground. What is the coin's velocity when it is at its highest point? 3.1 m/s
-9.81 m/s
9.81 m/s
0 m/s

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

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.
