Question

At the beginning of her fall, does the skydiver have an acceleration?

A) Yes, a constant acceleration.
B) Yes, but the acceleration changes.
C) No, zero acceleration.
D) No, acceleration is negligible.

Answer 1

At the beginning of her fall, a skydiver experiences an acceleration, although it changes over time.

Step-by-step explanation:

In the case of a skydiver at the beginning of her fall, the correct answer is B) Yes, but the acceleration changes.

When a skydiver jumps out of an airplane, they initially have a positive acceleration due to gravity. This means their speed increases in a downward direction. However, as they continue to fall, they eventually reach a point where the force of gravity is balanced by the force of air resistance. At this point, the skydiver reaches terminal velocity, and their acceleration becomes zero.

So, while the acceleration at the beginning of the fall is not constant, it does exist.
