The volume V of an ideal gas varies directly with the temperature T and inversely with the pressure P. A cylinder contains oxygen at a temperature of 310 degrees K and a pressure of 18 atmospheres in a volume of 120 liters. Find the pressure if the volume is decreased to 105 liters and the temperature is increased to 350 degrees K.

Round your answer to two decimal places.

A block of mass M is on a frictionless surface as shown below. It is attached to a wall by 
two springs with the same constant K. Initially the block is at rest and the springs unstretched. The block is pulled a distance A and then released. (a) What is the speed of 
the block as it passes through equilibrium? (b) What is the angular frequency ω of the 
motion? (c) If the two springs were replaced by one spring so that ω remains the same, 
what would its spring constant have to be? (d) If the two springs were kept, what would 
the mass have to be so that it has the same ω as a system comprised of a single block of 
mass M and spring with stiffness K?

1.   Two  objects of masses  m1  =  0.56 kg  and  m2  =  0.88 kg  are  placed on a  horizontal frictionless surface  and  a  compressed spring  of  force  constant  k  =  280 N/m  is placed between them  as in Fig. a. Neglect the  mass of  the  spring. The  spring  is not attached to either object and is  compressed a  distance  of 9.8  cm.  If the  objects are  released from rest, find the final velocity of each object as shown in Fig. b.
