A spring whose spring constant is 850 N/m is compressed 0.40 m. What speed will it give a 500. g ball when launched? 16.5 m/s
Suppose the spring is compressed twice as far. By what factor would the speed of the ball increase? x2

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
