Answer:
2.94 x 10⁵ Pa
Explanation:
m = mass of the car supported by four ires = 1200 kg
g = acceleration due to gravity = 9.8 m/s²
A = Area of contact for each tire = 100 cm² = 100 x 10⁻⁴ m²
n = Number of tires
P = Gauge pressure
Using equilibrium of force in vertical direction
n P A = mg
4 P (100 x 10⁻⁴) = (1200) (9.8)
P = 2.94 x 10⁵ Pa
Answer: A
Explanation: If you drop an object in the absence of air resistance, it accelerates downward at 9.8 m/s2.
