Parachute and terminal velocity

The graph shows the vertical speed of a parachutist. At which point did they open the parachute?

• A

• B

• C

• D

If a skydiver changes from a vertical to a horizontal position during freefall:

• His terminal speed would increase

• His terminal speed would decrease

• His terminal speed would stay the same

When a parachute canopy is opened more drag is created because:

• It has a large mass

• It has a large surface area

• It is travelling at terminal speed

• The person is now vertical

If this graph were to show a parachutist jumping from a plane, how would you describe the forces acting at point B.

• His weight is bigger than air resistance

• Air resistance is bigger than his weight.

• His weight and air resistance are balanced.
