A cannonball of mass 1kg is shot vertically upward from the top of a b

1.	A cannonball of mass 1kg is shot vertically upward from the top of a building with an unknown velocity v0(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.
Answer» t FIND the initial velocity of the cannonball, after that apply displacement formula to get the HEIGHT reached above the BUILDING, then subtract that height from 30M
