    A coin (5 grams), a small parachute (21 grams), and a hammer (710 grams) are all dropped from a height of 10 meters. The coin and the hammer take about the same amount of time to fall. Which statement describes the time it takes for the parachute to fall?(1 point)
Responses
It takes the same amount of time to fall because the effect of gravity is the same.
