Question

A skydiver steps out of his plane, and falls with a steady downward acceleration of 6.2m/s².

a) Find general expressions for the skydiver's velocity and position.

b) when the skydiver stepped out of the plane it was in a slow climb, rising at 0.5m/s. Use that information to write improved velocity and position expressions.

c) After falling for 8 seconds, the skydiver is 850m above the ground. Use that information to improve the position expression again.

d) How fast is the skydiver falling after 12 seconds?

e) If the skydiver's acceleration did not change, at what time would they reach the ground?
