Soapbox derby team. The car and driver have a maximum mass Mmax and
the wheel maximum radius is Rmax . Your job is to advise them on
the following issue: a) Heavy wheel and light body, b) Light wheel

2. [20| Consider the car stopping distance example we studied in Section 2.2, with the model 2 where d is the stopping distance, v is the velocity of the car before braking, tr is the response time, and k is a coefficient related to the ratio of the braking force and the mass fo the car. (a) [5] Fit the model (i.e, determine the parameters t and k) to the data in the first column and the last column of...

What does the second law of thermodynamics state about energy? When energy transforms, the energy breaks down from a neatly organized state to a state of disarray Thermal energy from a warm object will move into a colder object until all the thermal energy has been transferred. As heat disperses into a colder object, coldness disperses into the heat source until their temperatures are equal O When alowed to do so, localized energy disperses into places where less energy is...

There was a car accident. Someone stopped and the person
behind them rear ended them. The car that stopped slid away about
30 feet and the car that did the rear ending stopped right about
where the collision happened. Was this a perfectly inelastic
collision? Why or why not?
A perfectly elastic collision is one in which kinetic
energy is conserved. How exactly is kinetic energy not conserved
though? Sometime KE can be used up compressing/bending things and
making heat,...

6. Estimate the angular acceleration of the wheels on your car in a typical start from zero to 30 m/s. This does not mean some wild, unjustified number of radians/s?. It does mean making at least two numerical estimates and using them in at least 3 equations, all of which must be shown to get credit on this one. If you need some hints, check the Discussion section on Canvas. 7. The maximum pressure Portland cement concrete can withstand under...
