1) A speeding motorist traveling 30 m/s passes a stationary police officer. The officer immediately begins pursuit at a constant acceleration of 3 m/s2 . a) How much time will it take for the police officer to reach the speeder? b) What is the velocity of officer when he catches the speeder? c) Plot two graphs, show the displacement vs. time for both motorist and police in one graph and velocity vs. time for both of them in a the other graph.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
