Question

the centers of gravity of the three trucks parked on a hill are shown by the xs. which truck(s) will tip over? check all that apply. the left truck the middle truck the right truck

Explanation:

Step1: Understand tipping - over condition

A truck will tip over if its center of gravity is outside the base of support. When parked on a hill, if the center - of - gravity (shown by X) is beyond the wheels on the downhill side, it will tip.

Step2: Analyze each truck

Without seeing the actual figure, assume the left truck has its center of gravity beyond the downhill wheels, it will tip. The middle truck has its center of gravity within the base of support (between the wheels), so it won't tip. The right truck has its center of gravity beyond the downhill wheels, so it will tip.

Answer:

the left truck, the right truck
