A major-league pitcher can throw a baseball in excess of 44.6 m/s. If a ball is thrown horizontally at this speed, how much will it drop by the time it reaches catcher who is 18m away from the point of release.
One long wire lies along an x axis and carries a current of 42 A in the positive x direction, What is the magnitude of the resulting magnetic field at the point (0, 2.0 m, 0)
A 2.25×10^4 elevator is to be accelerated upward by connecting it to a counterweight using a light (but strong!) cable passing over a solid uniform disk-shaped pulley. There is no appreciable friction at the axle of the pulley, other than its mass..
