A 6.00?kg ball is dropped from a height of 13.0m above one end of a uniform bar that pivots at its center. The bar has mass 7.50kg and is 6.80m in length. At the other end of the bar sits another 6.00?kg ball, unattached to the bar. The dropped ball sticks to the bar after the collision.
How high will the other ball go after the collision?
If a circular wire loop of radius 10 were held in this magnetic field, what current would be induced in the loop
At its Ames Research Center, NASA uses its large "20-G" centrifuge to test the effects of very large accelerations ("hyper gravity") on test pilots and astronauts. In this device, an arm 8.84 {rm m} long rotates about one end in a horizontal plane..
