Bearings Jokes

The physics student went out, purchased some stopwatches, a number of ball bearings, a calculator, and some friends. He had them all time the drop of ball bearings from the roof, and he then figured out the height from the time it took for the bearings to accelerate from rest until they impacted with the sidewalk.
The math student waited until the sun was going down, then she took out her protractor, plumb line, measuring tape,and scratch pad, measured the length of the shadow, found the angle the buildings roof made from the ground, and used trigonometry to figure out the height of the building.
