1. The problem statement, all variables and given/known data 1) A typical automobile tire has a gauge pressure of around 30 Ib/in^2. How much is that in pascals? If a car weighs 8897N(=2000lb), how much area(SI units) on each tire is in contact with the road? 2) A swimming pool 5m wide by 10m long is filled to a depth of 3m. What's the total force exerted on the bottom due to the water? 3) GIven that most people cannot suck water up a straw any higher than about 1.1m, what's the lowest gauge pressure they can creat in the lungs? 2. Relevant equations F=PA F=P(4A) PA=F P= p(h2O)gh 3. The attempt at a solution 1) 2.1 x 10^5 Pa and .011m^2 are answers..I didn't get these answers though.. 2) 1.5 x10^6 n is the answer 3) -1.1 x10^4 Pa is the answer.. Please help me to get these answers by giving me steps and equations. Thank you!
