2. a. You are walking out on a frozen lake, and you begin to hear the ice cracking beneath you. As the best strategy for getting off the ice safely, you decide to spread your body and crawl. If your mass is B kg and your body area is D/10 m², calculate the pressure you apply to the frozen lake? d. When you visit the doctor's office, a nurse calls out your blood pressure as "B/C." in systolic blood pressure where is upper bound B and C is lower bound. What will be this value in Pascals, and do you have unhealthy blood pressure? e. A nurse needs to inject liquid medicine into your body by exerting a D/5 newtons force onto a hypodermic syringe. If the barrel of the syringe is 5.0 millimeters in diameter and the syringe's needle is 0.25 millimeters in diameter, how many newtons of force does the medicine come out from the needle into your body? f. A garden hose has two cross-sectional obstructed openings with a cross sectional area of X opening is D/10 m² and Y opening is D/100 m². What will be the ratio of speed of water coming outside in these two openings (X to Y)? What principles did you use here? B:27.0 C: 127.0 D:9.0

If an airplane is flying at 140 miles per hour east and turns in a smooth curve with a diameter of 3 miles, what is its centripetal acceleration in m/s2 ? SYW!!!
In 1959, Daytona Speed was added to the NASCAR racing circuit and introduced 31° banked curves for racing. This allowed stock cars to reach much higher speeds (around 200 mph) during a race. Today the steepest banked curves are found at Talladega Motor Speed Way at 33° with a turn radius of 1100 ft. The flattest track in NASCAR is Hew Hampshire Motor Speed Way with banked curves of 7° with a turn radius of 410 ft. a) Assuming no friction, what are the max speeds (in mph) without slipping toward the outer edge of the track at the Talladega and NH Motor Speedways? b) With friction (assume μs of 1.1 between the tires and the track)?
