Its physics, well you will have to use the kinematic equations. the one your are going to want to use is: v final = v initial + a(t final t initial) you will plug in your values so it looks like: 10 m/s = 40 m/s + a (0 5) Then solve for a: .25 = a(5s) a= 0.05 m/s^2

I did the math wrong, sorry. Instead of dividing 10 by 40 I should have subtracted so it would look like this: 10 m/s = 40 m/s + a(50 s) 30 m/s = a(5 s) 6 m/s^2 = a
