It is 8: 00 a. m. (a peak period) and you just entered the security line. to catch your plane you must be at the gate within 30 minutes. if it takes 12 minutes from the time you clear security until you reach your gate, what is the probability you will miss your flight?

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
