Question

A particle has:

A.) an average acceleration of 6 m/s2 if it goes from 2 m/s to 6 m/s in 2 seconds.

B.) an average acceleration of 4 m/s2 if it goes from 2 m/s to 6 m/s in 2 seconds.

C.) an average acceleration of 12 m/s2 if it goes from 2 m/s to 6 m/s in 2 seconds.

D.) an average acceleration of 3 m/s2 if it goes from 2 m/s to 6 m/s in 2 seconds.

E.) an average acceleration of 2 m/s2 if it goes from 2 m/s to 6 m/s in 2 seconds.

Answer 1

Acceleration is the change in velocity over time. So if I start at 0m/s and 2 seconds later I am going at 6m/s my acceleration is 3m/s. Let me know if that doesn't make sense

Answer 2

ummm not really

Answer 3

Ok well in your question the particle goes from 2 to 6 m/s right?

Answer 4

And it does that in 2 seconds.
