Homework Statement A Cubic meter of a gas at STP is heated to 180 degrees celsius. The pressure acting on the gas is kept constant. What is the new volume? Homework Equations V1/T1=V2/T2 The Attempt at a Solution Well, I plugged in the variables and came up with: 1/0=V2/180 Doing this...

All right, now in solving for the potential momentum of the car compared with the truck. using p=mv, I found the momentum of the truck to be Pt=mVt. I rewrote the equation so that Vt=m/Pt. I then found the momentum of the car to be Pc=1/5m x (√5 x Vt) <-- velocity of the car. I substituted the...

so... 1/2m(Vt^2)=1/2(1/5m)(Vc^2) 1/2m(Vt^2)=1/10m(Vc^2) 5(Vt^2)=Vc^2 Square root of 5 x Vt = VC?

Homework Statement A car and a truck have the same kinetic energy, but the car's mass is one fifth that of the truck. Compare the velocity and momentum of the car with those of the truck. Homework Equations KE=1/2mv^2 p=mv The Attempt at a Solution I am not really sure what to...
