Briefly explain how an electric generator works.

Car A rear ends Car B, which has twice the mass of A, on an icyroad at a speed low enough so that the collision is essentiallyelastic. Car B is stopped at a light when it is struck. Car A hasmass m and speed v before the collision.

A ball is thrown with a velocity of 20 m/s at an angle of 60 degrees above the horizontal. What is the horizontal component of its instantaneous velocity at the the exact top of its trajectory?

You pull on a wagon resting on the sidewalk. What will happen next. A. The wagon does not move because the wagon applies more force to you than you apply to the wagon. B. The wagon moves because you apply more friction to the ground. C.
