- Homework Statement
- A 4x4 car is moving with constant speed V through a depression on the ground which can be approximate to an arc of a circumference, the length of which is equivalent to the wheelbase (inter axis) of the vehicle and the depth to half of the diameter of the wheels so that when the front wheels come out of the depression the rear ones are entering it. In that moment the vehicle rears up: the front wheels leave the ground, the rear ones continue their march inside the depression. After having drawn a short parabola in the air, the front wheels fall back to the ground, at the same time as the rear ones come out of the depression, detaching themselves from the ground only slightly. If possible, answer the following questions justifying the answer or why you cannot answers:

- Why do the front wheels leave the ground?

- Why are the rear wheels only slightly leave the ground?

- Is the weight of the vehicle equally distributed on the 4 wheels?

- Will the parabola drawn by the front wheels at the exit of the valley respond to the hourly law Z(x)=V0t+12Gt2 ? Are there other elements to take into account in the equation of motion? If possible, please write the correct equation.

- Relevant Equations
- Z(x)=V0t+1/2Gt^2

I ask for help in interpreting this question. Thank you !
