An acceleration of 8.33 metres per second squared due west means the velocity changes by:
A8.33 seconds per metre west
B8.33 m/s west each second
C8.33 metres west each second
D8.33 m/s west in total
Answer & Solution
Correct answer: B. 8.33 m/s west each second
1. Reading the units aloud gives the meaning of the number.
2. An acceleration of that size due west means the horse increases its velocity by 8.33 metres per second due west each second.
3. That is 8.33 metres per second per second.
4. Metres alone would be a displacement, not a change in velocity.
