Round your answer to two decimal places. 4] The height in meters of a projectile can be modeled by h = -4.9^2+ vt +s where t is the time in seconds) the object has been in the air, v is the initial velocity (in meters per second) and s is the initial height (in meters). A soccer ball is kicked upward from the ground and flies through the air with an initial velocity of 4.9 meters per second. Approximately, after how many seconds does it land?
