Question

1. A parachutist is 800 feet above the ground when she opens her parachute. She then falls at a constant rate of 5 feet per second. Select the equation that represents this situation. h = -800t + 5 y = -5x + 800 h = 5t - 800 y = 800x + 5

Answer 1

h = -5*t +800

Explanation:

The initial value is 800 ft

She is falling at a rate of 5 ft per second

That would be -5ft/s

We can write this in the form

y = mx+b

h = -5*t +800 where t is the number of seconds and h is the height above ground
