At t = 0 seconds, a cart is moving with a velocity of 10 cm/s and an acceleration of 4.0 (cm/s)/s. Assuming its acceleration stays at this value, what will its velocity be 7.0 seconds later?

    Yeah. I just need someone to make sure I did it right. So it would be 4.0=(x-0)/7

    4*7=28 then you add in the 10 which gives you 38.

    Welcome. About the units, you need to take care that everything is in similar unit system.
