A 2,400 kg car drives north toward a 60 kg shopping cart that has a velocity of zero. The two objects collide, giving the car a final velocity of 4.33 m/s north and the shopping cart a velocity of 8.88 m/s north. What was the initial velocity of the car ?

Asystem containing an ideal gas at a constant pressure of 1.22×10^5 pa gains 2140 j of heat. during the process, the internal energy of the system increases by 2320 j. what is the change in volume of the gas?

The volume of a gas is halved during an adiabatic compression that increases the pressure by a factor of 2.5. what is the specific heat ratio? show the math steps .
