A cannonball of mass 15 kg is fired vertically upward from a cannon with an initial speed of 20 m/s. The cannonball travels upward, reaches a maximum height of 40 m, and returns to the ground. Now you decide to shoot a 30 kg cannonball vertically upward using the same cannon. If we assume that all cannonballs leave this cannon with an initial speed of 20 m/s, what maximum height does the 30 kg cannonball reach
