How to Win a Hot Wheels Derby on a Mobile Tape

If the force of the left wheel is greater than the right, this will create a clean moment that will turn the car to the right. However, this is not a problem for some touring cars. Suppose a car turns left and goes down the track diagonally (not straight down). Now there will be a force on the side of the wheels. This will push the wheel on one side of the car to the axle and move the other wheel away from the axle. It is possible that pushing and pulling the wheels can change the effective coefficient of kinetic friction so that the differential frictional forces rotate to the other side and back downhill. These are the lucky cars that have more chances to win.

What about the Wall?

Suppose a car turns to the left and moves to the left of the belt until it comes in contact with the side wall. He cannot continue to move to the left as there is an obstacle. By hitting it at a shallow angle, the wall can make a force to the sides to rotate it back “downhill”. However, if it continues to push against the side wall, there will be a frictional force between the car and the wall. This friction force will push the slope up and the net force will go down the slope. If this friction force on the wall is the right amount, the net force will be zero and the car will not accelerate. He will remain in the same position.

Does the speed of the tape type also apply?

In the analysis above, none of the forces depend on the speed of the motor belt. If a car is moving directly off the track, then the speed of the belt motor does not matter. But what about moving a car down? Clearly, in a real race with cars that can move in any direction, track speed matters. Okay, so let’s say we have two cars with the same speed (v) moving on a track. What happens when a car spins?

What are these speed labels? It turns out that speeds are relative to our frame of reference. Both cars have speed on the track. So AT A is the speed of the car relative to the track. What about track speed? This is measured by the ground reference frame. But what we want is the speed with which the cars move on the ground. To do this, we can use this speed transformation. (Here is a more detailed explanation.)
