Question

a cannon of a ship launches horizontally, from a height of 7 meters with respect to the level of the sea, a projectile with an initial speed of 900m / s. If the tube of the cannon is 25m long and it is assumed that the movement of the projectile inside the tube is uniformly accelerated, due to the constant force of the gases from the combustion of the powder, calculate: a) the acceleration of the projectile inside the cannon and the time invested by the projectile in traveling the cannon tube. b) The horizontal distance reached by the projectile from the moment it leaves the canyon until it enters the water.
