A friend asks you how much pressure is in your car tires. You know that the tire manufacturer recommends 35 psi , but it's been a while since you've checked. You can't find a tire gauge in the car, but you do find the owner's manual and a ruler. Fortunately, you've just finished taking physics, so you tell your friend, "I don't know, but I can figure it out." From the owner's manual you find that the car's mass is 1500 kg . It seems reasonable to assume that each tire supports one-fourth of the weight. With the ruler you find that the tires are 19 cm wide and the flattened segment of the tire in contact with the road is 15 cm long.

What answer will you give your friend?

Express your answer using three significant figures and in psi

    The speedometer on your car is broken. However you notice that the wheels of your car are rotating at 675 rpm (that reading is not broken on your car). Being a number geek, you know that the radius of your tires is 12 inches = 30 cm. Calculate the speed of the car (this is the same as the velocity of the tire rims). Please show all math steps. Thanks!

    While rotating the tires on your car you notice a rock [mass = 0.1 Kg] stuck in one. You learn online that the rock and the tire have a μ=0.6 between them and a maximum normal force equal to 140 times the rocks weight, and you find that your tire has a diameter of 24 inches. You turn on your car, put it in first gear, and start pushing the accelerator. At what “speed” on your speedometer does the rock...

    As you approached the I-74 exit in your uncle's little red sports car convertible you happened to notice a cat crossing the road. Not that you have any particular love of cats (especially this one whose snooty disposition seems to beckon for a game of chicken) you swerve out of the way spilling scalding hot coffee all over your new summer duds. Unknown to you at the time, the auto mechanic, having had an uneventful social life and being consequently...

    5. If you put air in your tires in La Paz, Bolivia, and your pressure gauge is reading 25 psig, what is the absolute pressure inside the tire, in psia? (The standard atmospheric pressure in La Paz is about 62 kPa!) Answer: between 30 and 35 psia. 2. A manometer like the one we drew in class has water in the column. The side that is open to standard atmospheric pressure is 20 cm lower than the side open to...
