A cannon has a mass of 219 kg and is loaded with a cannonball of 20 kg. It is initially stationary. When fired the cannon has a recoil velocity equal to -6. 2 m/s to the left. What must be the velocity of the cannonball?.

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) sketch the trajectory using an appropriate coordination system. b) how long for the projectile to reach the ground. c) how far did projectile travel horizontally before striking the ground. d) determine the projectilex & y position at t-1.3s e) determine the magnitude and direction of projectile velocity at t= 1.3s f) determine the magnitude and direction of projectile acceleration at t-1.3s
