Homework Statement



Calculate the average velocity for a remote controlled vehicle that starts with a speed of 1.0 m/s [forward] and then accelerates at 0.08 m/s2 [backward] for 4.0 s


Homework Equations



Vavg=deltaD/deltaT

The Attempt at a Solution



I'm unsure of how to go about this even though it seems its an easy question. Is there enough information to even solve it? Wouldn't i need the time at which it travels forward? Thanks for any help

Hi adhoward24! :smile:

(have a delta: ∆ and try using the X2 tag just above the Reply box :wink:)

I don't understand this …

you know its speed at t = 0, and you know ∆t = 4.

Hint: find an equation for ∆D, and divide it by ∆t. :wink:
