A spring gun with a spring constant, k = 120 N/m, is placed at the edge of a table that is a distance H = 1.5m above the floor and the apparatus is used to shoot marbles with a constant velocity in the horizontal plane. The spring is initially compressed by a distance, X = 0.20 m, and then released. The mass of each marble is m = 0.005 kg.
a. How much work is done by the spring on the marble?
b. What is the speed of the marble at the edge of the table (when it leaves the launcher)?
c. What is the total energy of the marble at the edge of the table with respect to the floor level?
d. How much time will it take the marble to reach the floor level from the table?
e. What is the horizontal range of the marble?
f. What is the kinetic energy of the marble just before it strikes the floor?
