Question

How do I find the acceleration at 1.0s and 7.5 m/s [W]?

Answer 1

I know I have to find the slope but do I do it as: 7.5 - 1.0/0-1.0? 'Cause the answer in the back of the book says: 7.5 m/s^2

Answer 2

what information does the graph show us?

Answer 3

7.5 meters per sec sounds alot like velocity, as long as we are staying in the same direction. and its constant.

v(t) = 7.5 acceleration would then be the derivative of this, but that would turn out to be 0 since velocity is not changeing at all with respect to time ... hmmm

Answer 4

its just hard to tell what the information provided means
