The graph shows how the vertical velocity of a parachutist changes from the moment the parachutist jumps from the aircraft until landing on the ground. Using the idea of forces, explain why the parachutist reaches a terminal velocity and why opening the parachute reduces the terminal velocity.

Sagot :

Answer:

once the parachute is opened, the air resistance overwhelms the downward force of gravity. The net force and the acceleration on the falling skydiver is upward. ... 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.

Explanation:

As the parachute is opened the air and due to the downward force of gravity the resource is upwards hence the skydiver falls slowly.

Who Β is a parachutist?

A parachutist is one who uses a parachute when making a skydive. Once the parachute is opened the air offers some resistance and due to the downward force of gravity.

The net force and force of acceleration are on the skydiver and a, as a result, he falls slowly. As the speed gets decreased the amount of air resistance will also decrease.
