Question

HEYOOO PEEEPPPSS As skydivers fall through the air, a resisting force builds up underneath them. This air resistance decreases their acceleration toward the ground, making them reach a constant velocity as they fall. This is called terminal velocity. The average terminal velocity for a skydiver is about 200 km/hr.

This speed is much too fast for a skydiver to land safely. A safe speed for a skydiver to land at is only 30 km/hr.


Resistance from the air isn’t enough to slow down a skydiver to a safe landing speed. The skydiver needs a parachute.




Does the parachute provide an acceleration for the skydiver? Explain your reasoning.

Answer 1

Answer:Your parachute allows you to descend more slowly because it lowers terminal velocity by increasing your air resistance. Most parachutes are designed to create a large amount of drag and allow you to land at a safe, low speed.

Explanation:Again this is going to be the same explanation as the other one a said in the same question but it duplicated so here it is: this is just to try and contradict the other one because the other one above me doesn't really go into explaining what is the role of the parachute so hopefully this helps bettery in clarifying details in some way shape or form.

Answer 2

Answer:

The net force and the acceleration on the falling skydiver is upward. An upward net force on a downward falling object would cause that object to slow down. The skydiver thus slows down. As the speed decreases, the amount of air resistance also decreases until once more the skydiver reaches a terminal velocity.
