Reference no: EM13257864

A toy cannon uses a spring to project a 5.30 g soft rubber ball. The spring is originally compressed by 5.00 cm and has a force constant of 8.00 N/m. When it is fired, the ball moves 15.0 cm through the barrel of the cannon that is angled upwards at 40.0 degrees, and a constant frictional force of 0.0320 N exists between barrel and ball.

(a) With what speed does the projectile leave the barrel of the cannon? m/s

(b) At what point does the ball have maximum speed? cm (from the starting position)
