A graduated cylinder filled with water rests upside down in a container of water at 0 C. The water is 7.00 cm deep. Attached to the base of the cylinder is a small ring (but since the cylinder is upside down, the ring is at the highest elevation, available for grabbing). The base of the cylinder has mass 10.0 grams with ring included. The cylinder itself has radius 3.00 cm, height 40.0 cm, and mass 100.0 grams (including the base and ring). Bridgette has a scale that can read hanging weight (but, as so often happens, reads in grams instead of Newtons). She hooks the scale to the ring on the bottom of the cylinder and lifts, so that the base of the cylinder lifts 5.00 cm, but the other end of the cylinder remains beneath the surface of the water. She is amazed that the cylinder remains full of water, seemingly all the way to the base. What is the reading on the scale? (The mass density of the cylindrical part of the graduated cylinder is 1.00 grams per cm3.)

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.
