Question

question 14 (1 point)
suppose a skydiver jumps from a high - flying plane. what is her acceleration when she she reaches terminal velocity?
it is essentially zero.
it is in the upward direction.
it is approximately 9.8 m/s2 downward.
it is a constant pointing upward.

Explanation:

Terminal velocity is reached when the upward force of air resistance equals the downward force of gravity (weight) on the skydiver. According to Newton's second law (\(F = ma\)), if the net force (\(F_{net}\)) is zero (since \(F_{air\ resistance}=F_{gravity}\)), then acceleration \(a=\frac{F_{net}}{m} = 0\) (because \(F_{net} = 0\) and mass \(m\) is non - zero). So the acceleration at terminal velocity is essentially zero.

Answer:

It is essentially zero.
