Suppose you find yourself in your friend's third floor apartment building when you smell smoke coming from outside the door. you open the door an see nothing but flames protruding from the hallway. realizing that your only means of escape is through the window of the apartment, your freind agrees to donate many pairs of nylons which you tie together to form a makeshift rope. this nylon rope(no pun intended) can withstand a maximum tension of 500 n without breaking. you have a mass of 70kg on this particular day.
a) why can't you slide down the rope at a near constant speeed?
b) what is the smallest prssible acceleration you must achieve in order to slide down the rope without it breaking? ans: 2.9m/s square

Awelder using a tank of volume 7.50×10^-2 m^3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.30×10^5 pa and temperature of 37.1 ∘c. the tank has a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 23.1 ∘c, the gauge pressure of the oxygen in the tank is 2.00×10^5 pa . a) find the initial mass of oxygen. b) find the mass of oxygen that has leaked out.
