# Lunar Elevation

Calculus Level 3

A spring launches a projectile straight up from the surface of the Moon. The projectile leaves the surface with an initial velocity of $$20 \text{ m/s}$$. How many meters above the surface of the Moon will the projectile be at 20 seconds after its launched?

Consider the gravity at the surface to be $$1.62 \text{ m/s}^2$$ Consider the acceleration due to gravity to be constant along the path of the projectile.
