Driving 30.7 m/s in your car you see a dog up ahead and slam on your brakes. You stop just before hitting the dog after skidding

Nitella [24]

Answer: 2.74

Explanation:

We can solve this problem using the stopping distance formula:

$d=\frac{(V_{o})^{2}}{2 \mu g}$

Where:

$d=132.1 m$ is the distance traveled by the car before it stops

$V_{o}=30.7 m/s$ is the car's initial velocity

$\mu$ is the coefficient of friction between the road and the tires

$g=9.8 m/s^{2}$ is the acceleration due gravity

Isolating $\mu$ :

$\mu=\frac{2dg}{(V_{o})^{2}}$

Solving:

$\mu=\frac{2(132.1 m)(9.8 m/s^{2})}{(30.7 m/s)^{2}}$

$\mu=2.74$ This is the coefficient of friction
