A bicycle traveling in the plus x direction with a constant velocity of 4.50m/s. At time t = 0s the bicycle passes a car and the car starts accelerating in the plus x direction at 1.75m/s2 .At what time will the bicycle and car be traveling at the same velocity? At some time later, the car passes the bicycle, how long has it been since the bicycle passed the

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.
