# Calculat the negative acceleration on a vehicle during skid.

#### NeedHelpBro

1. Homework Statement
Total Stopping distance = 50 meters
Driver Reaction Time = 1 Seconds
Coefficient of sliding friction = 0.58

2. Homework Equations
D=(Total Distance)=V^2/2μg

3. The Attempt at a Solution
v≈36.66 (Initial Velocity) but im sure what do after this step to find the negative acceleration, it would help if you just provide the formula to use.

Aren't you studying physics? Why can't you find a formula in your text? You wrote some formula in the OP. Why isn't that the correct formula? Where did it come from? Were there other formulas there?
