Question

What do you do if your vehicle is trapped on a slippery or a sandy road? What is the physics involved?

Answer 1

Driving on country roads requires four-wheel drive. If you become stuck in deep sand or mud, don't try to drive yourself out. Excessive tyre spinning will almost certainly dig a bigger hole. Getting unstuck from sand or mud depends on momentum. One approach is to rock your automobile backwards and forwards to gain velocity. To increase traction and momentum, place a car mat, sticks, leaves, gravel, or rocks in front of and under your drive wheels. Maintain your momentum until you reach firm ground.
