Question

The chart shows masses and velocities of four objects.

A 3-column table with 4 rows titled Motion of 4 Objects. The first column labeled Object has entries W, X, Y, Z. The second column labeled Mass (kilograms) has entries 12, 15, 18, 28. The third column labeled Velocity (meters per second) has entries 5, 8, 2, 10.
Which lists the objects in order, from least to greatest momentum?

W, X, Y, Z
Z, Y, X, W
Z, X, W, Y
Y, W, X, Z

Answer 1

Compute momentum p = m v:
- W: 12×5 = 60
- X: 15×8 = 120
- Y: 18×2 = 36
- Z: 28×10 = 280

Ordered least to greatest: Y (36), W (60), X (120), Z (280). So: Y, W, X, Z.
