Acar was skid to a half a uniform rate of -9.4 m/s ^2 squared if the measure skid marks that are 34 m long with what speed is the car going just before the driver slammed the brakes

vi = 25.28 m/s

Step-by-step explanation:

a = -9.4 m/s²

x = 34 m

vf = 0 m/s

vi = ?

We can apply the equation

vf² = vi² + 2*a*x

⇒     vi = √(vf² - 2*a*x)

⇒     vi = √((0 m/s)² - 2*(-9.4 m/s²)*34 m)

⇒     vi = 25.28 m/s

i believe the answer is d.

hope it you! : d

what i would say the best answer is a. 40.5
