Two cylinders are connected. The first has an unknown volume but is in perfect vacuum. The second is filled with argon, has a volume of 300 ml, and a pressure of 2 bar. If a valve is opened
between the two cylinders, the final pressure is 1.4 bar. What is the volume of cylinder 1? (you may
assume the temperature is constant) (3 pts)

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
