Final answer:
To find the contact area of each tire with the road, divide the total force by the pressure. The total force can be calculated by dividing the weight of the car by the number of tires. Substitute the given values to find the contact area.
Step-by-step explanation:
To find the contact area of each tire with the road, we can use the formula:
Contact area = Total force / Pressure
Given the mass of the car is 1520 kg and each tire bears one-quarter of the total load, the total force can be calculated as:
Total force = Weight of the car / Number of tires
Using the equation F = ma, where F is the weight of the car, m is the mass, and a is the acceleration due to gravity, the weight of the car is:
Weight of the car = mass x acceleration due to gravity
Finally, we can substitute the values and calculate the contact area.
