Paul Stender’s car has a rocket attached to it. While on, the rocket provides a thrust force of 51,500 Newtons. The car has as mass of 3,222kg. The coefficients of friction with the road and the tires are μk=.321, μs=.432, μr=.111, and the coefficient of drag is 0.800. The car is 3.0 meters long, 2.0 meters wide and 1.5 meters tall. The density of air is ρ=1.3kg/m3. Remember that the equation for the force of drag is: D = ½ρAC_dv². IN VPYTHON:
Create a program that keeps track of for every tenth of a second for the first 5 seconds…:

• …the amount of chemical energy burnt by the rocket
• …the amount of energy that is turned into thermal energy through wind drag
• …the amount of energy that is turned into thermal energy through rolling friction
• …The amount of energy that ends up as Kinetic Energy

You may assume a 100% efficient chemical process in the rocket. You may also assume that the mass change of the rocket is negligible.

Hi,

I can do the coding, but I'm at a loss for the physics behind the question. I don't know what qualifies as the total energy, or how to find it in this situation.

Thank you.
