1)On a cold winter day, a penny (mass 2.50 g ) and a nickel (mass 5.00g ) are lying on the smooth (frictionless) surface of a frozen lake. With your finger, you flick the penny toward the nickel with a speed of 2.30 m/s .

-The coins collide elastically; calculate both their final speeds. vpenny, vnickel. answers in m/s
-What are the directions of their final velocities?

2)Forensic scientists can measure the muzzle velocity of a gun by firing a bullet horizontally into a large hanging block that absorbs the bullet and swings upward. (See the figure below.) The measured maximum angle of s
