A cannon is placed on a movable cart (total mass = 50 kg) which can slide on a frictionless surface. The cart is given a velocity of 2msin the +ˆxdirection. While moving, the cannon fires a cannon ball of mass 1 kg which travels in the +ˆxdirection at 20ms. (a) What is the final speed of the cannon on the cart after firing? (b) Repeat the problem, only now the cannon fires the cannonball in the +ˆydirection.
