For the velocity-time graph attached, what is the average acceleration between 60 s and 120 s?

A. +13.6 m/s^2

B. +21.5 m/s^2

C. +29.4 m/s^2

D. +1,700 m/s^2

How do I calculate this? :/

Acceleration is the rate of change of velocity or the slope of the velocity vs time graph. Another way of asking this question would be; what is the slope of the line between 60 and 120 seconds?

Boy this is tough, they don't give you very clear points.
To me, it looks like we have: (60, 800) and (120, 2700)

Yeah, no clear points :(

I saw it as 2750 haha but I got 32.5 and with 2700, I get 31.67, so would the closest answer be C?

Yes I would agree.
