1.	For an initial speed of 10 m/s, how many launch angles will result in a range of 1 meter? Just one? Or more? You may need to type in a launch angle to get closer to a 1-m range.

2.	With no air resistance, how does the maximum height depend on the initial velocity? If the initial velocity is doubled but the launch angle is kept the same, how does the maximum height of the projectile change?

3.	How does the range of the projectile depend on the initial velocity?

4.	How does the time the projectile spends in the air depend on the initial velocity?
