A ball is dropped from the top of 8 m building. It bounces back half the drop. So when it will be still how many distance would it have travelled.

Which is not a source of noise pollution? a)airplanes b)acid rain c)machines d)cars

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

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.
