A 10 kg cannonball initally at rest is launched with a constant explosive force of 300,000 N for a short intervak time of 0.004 seconds. The cannonball is angled to fire at a 40 degree angle. Calculate the maximum height of the cannonball. Assume that air resistance is negligeble, the cannonball leaves the cannon from a height of zero meters, and the force due to gravity when the cannonball is launched is negligible.
