# How do you determine the minimum stopping distance of a motorcycle, given its velocity and the kinetic coefficient of friction?

##
A motorcycle moving at #25.0m/s# slides to a stop. Calculate the minimum stopping distance if the kinetic coefficient of friction between the tire and the road is #0.7# .

A motorcycle moving at

##### 1 Answer

Minimum stopping distance = 45.49m

#### Explanation:

The friction between the bike and the road will be

If this is the only force acting on the bike, then by Newton's 2nd law

so dividing both side by

We can now use the equation of motion:

We know the initial velocity,

So
