Help with a VT Graph: Acceleration & Deceleration Explained

[GCSEsoon]

I need to do a VT graph showing a parachute jump, I need an explanation about the graph too.

Homework Equations

None

My Attempt:

From point 0-2 the jump is accelerating largely at a constant uniform. From point 2-4 the acceleration remains at a constant velocity. From point 4-6 the gradient decreases at a constant speed until it reaches zero.

Thanks a lot,

What is it you are attempting to show with your graph. Perhaps a little more of an explanation of your thinking about your graph is in order?

What happens when the chute deploys? The diver stops at constant velocity or slows to a final velocity of descent?

At the ground, how fast will the jumper stop? 2 seconds to hit the ground and slow his impact?
