1) A spring launcher is used to send a toy car through a loop-the-loop, as shown below. The spring has spring constant k = 485 N/m, the car's mass is 30 grams, and the diameter of the circular loop is 0.32 m. Neglect friction. How far must the spring be compressed in order for the car to be able to make it all the way around the loop without falling? (Hint: The speed of the car at the top of the loop is not zero. Think about what the speed must be if only the car's weight is acting as the centripetal force.) WWW.C 0.32 m
