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.

A rocket has a mass of 1.40×04 kg and its engine has a thrust of 200×105 N. If its engines fire in the vertical direction for 1 min starting from rest, to what vertical height would it rise in the absence of air resistance? (To simplify things, assume the mass is constant. However, in reality the mass of rockets decreases substantially while rising)

A car needs to be towed and is attached to the tow vehicle by a 3.5m long 18mm diameter nylon rope. The tow vehicle is moving 5km/hr and takes up the slack in the rope which results in a sudden load being applied to the rope. The tow vehicle has a mass of 1.8tonnes and the car being towed is initially stationary. If the towing vehicle is instantly slowed to 0.5km/hr by the shock load, (E=2GPa for the rope) determine:...
