i got a few questions here.a baseball player hits a baseball from a height of 1m above the ground and its height is given by the equation h=-3t squared=12t+15, when h is the height in meters above the ground, and t is represent ed in seconds,is its time in the air. when, to the nearest tenth of a second, will the ball strike the ground




The path of a soccer ball after it is kicked from a height of 0.5m above the ground is given by the relation h=-squared + 1.1d+0.5, where h is the height above the ground and d is the horizontal distance, both in meter's.
a) how far has the soccer ball traveled horizontally, t the nearest tenth of a meter \, when it lands on the ground ?
b0 fond the horizontal distance when the soccer ball is at the a height of 1.5m above the ground.
