use the general equation of motion with constant acceleration:
---
r(t) = r0 + (v0)t + (at^2)/2
---
where:
r(t) = position at time t (meters)
r0 = position at time 0 (meters)
v0 = velocity at time 0 (m/s)
a = constant acceleration (for gravity in the metric system use a = -9.81 m/s^2)
t = time (seconds)
---
r(t) = (-4.905)t^2
---
graph:
x-axis is time in seconds
y-axis is distance in meters
