In physics class, Jon stands on a ladder and drops a hammer and a feather while Keisha makes a video recording of the experiment. The mass of the hammer is 0.454
kg and the mass of the feather is 2 g. Using the video recording, Jon and Keisha calculate the accelerations of each object at different times, as shown in the table.
Time (s)
Acceleration of Hammer (m/s2
Acceleration
Feather (m/s)
0.1-0.2 9.8
9.8
0.2-0.3
9.7
9.5
0.3-0.4
9.7
6.8
0.4-0.5
9.8
0.8
Which statement best explains the difference between the hammer and the feather's rates of acceleration?
The feather's greater inertia decreases its acceleration.
The hammer's greater weight increases its acceleration.
The hammer's greater momentum increases its acceleration,
