When firing a projectile on level ground, the maximum range is achieved when the launch angle is 45 degrees. What if the projectile lands at a level higher than its launch position? What launch angle, measured from the horizontal, maximizes the range?

• 45 degrees (41%)
• an angle larger than 45 degrees (21%)
• an angle smaller than 45 degrees (9%)
• not enough information is given to say (29%)

The red ball is launched at 45 degrees. You can see that it does go furthest on level ground, but the ball launched at an angle higher than 45 goes furthest when the landing point is higher than the launch point.
