A student says that a speed of 50 m/s is faster than a speed of 140 km/h because the number is bigger. What would you say to them?/3

He is wrong. 50 m/s is greater than 140 km/h

Explanation:

For comparing the values, both need to be of the same units.

Therefore, converting unit,

140 km/h = 140 x 5/18 m/s = 350/9 m/s or 38.888... m/s(approx.)

As 50>38.888

Therefore, the student is wrong

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.
