Question

The chart shows data for four moving objects.

A 4 column table with 4 rows. The first column is labeled Object with entries, W, X, Y, Z. The second column is labeled Initial Velocity in meters per second with entries, 11, 10, 12, 20. The third column is labeled Final Velocity in meters per second with entries, 29, 34, 40, 28. The fourth column is labeled Change in Time in seconds with entries, 6, 12, 7, 8.
Which object has the greatest acceleration?

W
X
Y
Z

Answer 1

Compute acceleration a = (final − initial) / time:

- W: (29−11)/6 = 18/6 = 3 m/s²
- X: (34−10)/12 = 24/12 = 2 m/s²
- Y: (40−12)/7 = 28/7 = 4 m/s²
- Z: (28−20)/8 = 8/8 = 1 m/s²

Greatest acceleration: Y.
