Best ResponseYou've already chosen the best response.0You need t, time of change to find acceleration. A= (VfVi)/t . Without t, you need the distance it moved when changing speed then. and use T=d/(VfVi) .

Best ResponseYou've already chosen the best response.0i think the question is about the sign of the acceleration, if your velocity goes from a higher positive value to a lower positive one acceleration must be negative: \[a=\frac{V_fV_i}{\Delta t}=\frac{610}{\Delta t}=\frac{4}{\Delta t}<0\] since the time variation \(\Delta t\) is always positive!

Best ResponseYou've already chosen the best response.0@Harry21 it is, i was just pointing out that the problem is not asking to find the acceleration value
