HEYOOO PEEPS 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.

2. What is the role of the parachute? Explain your reasoning.

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.
