Hopping into your Porsche, you floor it and accelerate at 12 m/s2 without spinning the tires. Determine the minimum coefficient of static friction between the tires and the road needed to make this possible.

Solution 5P

Step 1 of 3</p>

The objective here is to determine the minimum coefficient of static friction between the tyres and the road which is required to produce the given acceleration without spinning the tyres.

Step 2 of 3</p>

Given that Acceleration,

By definition, the force of static friction is related to the weight of the body or the reaction force as,

From the relation , we write,

Which implies,

Therefore,
