Question

"What is the area of a car that touches the road if the car's weight on that tire is 3072 N and the pressure exerted on the road is 48 Pa?"

A) 64 square meters
B) 96 square meters
C) 144 square meters
D) 384 square meters
E) None of the above.

Answer 1

The area of the car tire that touches the road is found by dividing the car's weight on that tire (3072 N) by the pressure exerted (48 Pa), resulting in an area of 64 square meters.

The area of a car tire that touches the road can be found using the equation for pressure, which is the force divided by the area (Pressure = Force / Area). Given that the weight (force) on the tire is 3072 N and the pressure exerted on the road is 48 Pa, the area = Force / Pressure = 3072 N / 48 Pa = 64 square meters. Thus, the correct answer is A) 64 square meters.
