Question

The table shows information about four students who are running around a track.

A 3-column table with 4 rows titled Motion of Students. The first column labeled Student name has entries Autumn, MOhammed, Lexy, Chiang. The second column labeled Mass (kilograms) has entries 50, 57, 53, 64. The third column labeled Velocity (meters per second) has entries 4, 3, 2, 5.
Which statement is supported by the information in the chart?

Autumn has more kinetic energy than Chiang.
Mohammed has less kinetic energy than Autumn.
Lexy has more kinetic energy than Mohammed.
Chiang has less kinetic energy than Lexy.

Answer 1

Kinetic energy = 1/2 m v^2.

Calculate:
- Autumn: 0.5·50·4^2 = 400 J
- Mohammed: 0.5·57·3^2 = 256.5 J
- Lexy: 0.5·53·2^2 = 106 J
- Chiang: 0.5·64·5^2 = 800 J

Only the statement "Mohammed has less kinetic energy than Autumn" is supported.
