A Hot-Wheels track. must include a starter, loop, jump and dosed turn. The starter should contain a spring and you should use Hooke's law when designing what the starter looks like. The loop should be circular. The jump will consist of a ramp. You must choose all the parameters needed to the course. Ignore air resistance throughout the task.

guide:

In each section, it is important to have a clear description and reference to the physical laws on which it is based.

A)

 Choose constants (mass car, spring constant, length spring, radius of loop, angle and length of the ramp to the jump and angle and radius of dosed turn so that the car gets through the track. Arguments that the car can drive through the track Use analytical calculations in the argumentation Sketch the path Comment on critical points in the path.

B)

Calculate the energy in the system (analytical) and plot the ratio between potential and kinetic energy through the race (start, loop, jump and turn). Discuss what happens to the energy if we take into account the friction between the car and the surface.

C)

Calculate the length the car jumps. Discuss how the angle and length of the ramp to the jump changes the length. Which angle gives the longest jump?

D)

Calculate the angle and radius of the dosed turn and discuss the acceleration through the turn.

 E)

 Clear layout, correct units on plot and calculations.
