Which represents the greatest acceleration? 200 m/s

200 cm/s2

0.020 km/s2

0.002 km/s2

(3) 0.020km/s²

Explanation:

The option with greatest acceleration is the one with greatest magnitude.

To do this, we have to analyse each if the given options.

1. 200m/s.

This doesn't represent acceleration because acceleration is not measured in m/s. Rather, this option is a measure of velocity..

2. 200 cm/s²

[Convert to m/s²]

= 200 / 100 m/s²

= 2 m/s²

3. 0.020 km/s²

[Convert to m/s²]

= 0.020 * 1000m/s²

= 20m/s²

4. 0.002 km/s²

[Convert to m/s²]

= 0.002 * 1000 m/s²

= 2m/s²

By comparison options 1 through 4, option (3) has the highest magnitude of acceleration.

Hence, 0.020km/s² is the highest acceleration
