A car weighs 15,000 N and it’s tires are inflated to the pressure of 190 kg pascals. How large is the area of the cars tires that are in contact with the road
To find the area of the car's tires that are in contact with the road, we need to use the formula:
Pressure = Force/Area
We know that the pressure is 190 kg/m² (which is equivalent to 190,000 pascals) and the force is 15,000 N. Let's denote the area of the tires in contact with the road as A.
Plugging in the values to the formula, we have:
190,000 pascals = 15,000 N / A
Rearranging the equation to solve for A, we get:
A = 15,000 N / 190,000 pascals
Simplifying the right-hand side of the equation, we have:
A ≈ 0.079 m²
Therefore, the area of the car's tires that are in contact with the road is approximately 0.079 square meters.
