David asks…A car slows down uniformly from a speed of 28.0 m/s to rest in 4.50 s. How far did it travel in that time?I used the formula a=v-v0/t and x=x0+v0+v0t+1/2at^2.
Here is my whole problem and how I did..... But my answer is wrong.
28-0 / 4.5 = 6.222222222222222222222222222222222222.
Next I did x= 0+28+28(4.5) + 1/2 (-6.2)(4.5)^2
That equals 91.225...
What did I do wrong?admin answers:Omg i just learned it and have a test on it tmrw..i dont have the formulas in front of me but this
