PROBLEM 13.127 A truck is traveling down a road with a 4-percent grade at a speed of 80 km/h when its brakes are applied to slow it down to 30 km/h. An antiskid braking system limits the braking force to a value at which the wheels of the truck are just about to slide. Knowing that the coefficient of static friction between the road and the wheels is 0.60, determine the shortest time needed for the truck to slow down.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

PROBLEM 13.127
A truck is traveling down a road with a 4-percent grade at a speed of 80 km/h when its brakes are applied to
slow it down to 30 km/h. An antiskid braking system limits the braking force to a value at which the wheels of
the truck are just about to slide. Knowing that the coefficient of static frietion between the road and the wheels
is 0.60, determine the shortest time needed for the truck to slow down.
