Question

For science project Sarah has been instructed the test for different methods of slowing down the rate of tennis ball falls from 10 ft above the ground. She is working with Janice and Jose who are timing and recording the tennis ball drops.

A) dropping it outside on a windy day
B) tying a parachute cut from a plastic bag
C) gluing two large feathers to the top of the bone
D) punching a few holes into the surface of the ball

Which of these four methods most likely slow the rate of the fall of the ball?

I chose a please check my work please thank you

Answer 1

Option B (tying a parachute cut from a plastic bag) is the most likely to slow the rate of fall of the ball as it increases the air resistance acting on the ball as it falls. This increases the amount of air resistance and slows down the fall of the ball. Options A, C, and D do not increase the air resistance acting on the ball and are less likely to slow down the rate of fall.
