Question

How will a skydiver's velocity change when a parachute first

opens?
a The speed will suddenly decrease.
b The direction of the velocity is now upward.
c The acceleration will stay the same.
d The speed will not change.

Answer 1

A. When falling from a high speed, opening the parachute will cause the high speeds to slow down and cause you to fall slower hence why the parachute is needed to land safely

Answer 2

A, When the parachute opens, the air resistance increases. The skydiver slows down until a new, lower terminal velocity is reached.
