A toy cannon uses a spring to project a 5.23-g soft rubber ball. The spring is originally compressed by 5.05 cm and has a force constant of 7.92 N/m. When the cannon is fired, the ball moves 14.2 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.032 1 N on the ball.
With what speed does the projectile leave the barrel of the cannon?
a. 2.68 m/s
b. 1.58 m/s
c. 2.40 m/s
d. 1.38 m/s

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
