Assume the graph represents the distance (in m) fallen by a skydiver t seconds after jumping out

Question:

Assume the graph represents the distance (in m) fallen by a skydiver t seconds after jumping out of a plane. 

a. Estimate the velocity of the skydiver at t = 15.

b. Estimate the velocity of the skydiver at t = 70.

c. Estimate the average velocity of the skydiver between t = 20 and t = 90.

d. Sketch a graph of the velocity function, for 0 ≤ t ≤ 120.

e. What significant event occurred at t = 30?

УА 1600 1200 800 400 40 80 100 120 60 Time (seconds) Distance (meters)
