A projectile travels through the air with position and

*where*

*is horizontal displacement and*

*is height above the ground where both are measured in meters and*

*is in seconds.*

When does the projectile hit the ground?

When does

?How far does the projectile travel during its trip through the air? That is, calculate the length of the path of the projectile.

What is the maximum height of the projectile?

This is when

.What are the acceleration and velocity vectors of the projectile at time

seconds?
