4. A cannonball of mass 1kg is shot vertically upward from the top of a building with an unknown velocity vo(m/sec). After 2 seconds, the ball reaches its maximum height 30 meters from the ground. Neglecting the air resistance and taking the gravitational acceleration g to be 10(m/sec²), find the height of the building. 6 10 12 14
