Problems 14 - 16: A cannon is fixed to a rolling cart. The combined mass of the cannon and cart is 500 kg. A 1.0 kg cannonball is inserted into the cannon. The cannon is pushed in a straight, horizontal line until it achieves a speed of 6 m/s. The effects of air resistance and rolling resistance are negligible. 14. As the cart is rolling, the cannon is fired. The force acting on the cannonball is experimentally determined to be of the form: F(t) = A-sin(25xt) (N) where A is the amplitude of the force function. If it takes 0.02 seconds for the cannonball to exit the cannon immediately after firing, what is the impulse delivered to the cannonball ( in terms of A)?
