Background Information

MSXII's centre of gravity is to far back in the car, and the brakes need to compensate for the weight imbalance. In order to make braking more efficient, weight needs to added to the front of the car to balance it. However, the amount of weight added should be calculated, so that the car is balanced and not front heavy.

Requirements

1. Borrowing the tire scales from the Formula Race Team

2. Jacking up the car and placing the scales under each tire, one at a time

3. Recording the weight of the car
