You go with your little brother to a drag strip where cars race. He is into this stuff and brings his stopwatch. The purple car starting from rest travels a quarter of a mile (1320.0 ft) in 8.06 seconds. What was the acceleration?

What would the equation be?

anonymous · Answer

d= Vi*t +1/2 *a *t^2   

if Vi =0 :  d= 1/2 *a *t^2   

1320 = 1/2*a*(8.06)^2
