2_______________

For how long will the projectile remain airborne? (sec) HINT: Quadratic Solver.

3_______________

What is projectile’s range? (m)

4_______________

How high in the air will the projectile rise, relative to the valley floor? (m)

5_______________

4.0 sec into the launch, what is the projectile’s height above the cannon? (m/s)

6_______________

4.0 sec into the launch, what is the projectile’s VH and VV ? (m/s)

7_______________

4.0 sec into the launch, what is the projectile’s vector velocity ? (m/s, (+/-) ° )

8_______________

What is the projectile’s vector velocity as it is about to land? (m/s, (+/-) ° )
