The maximum braking force that can be applied to the car having a mass of 500kg is 8820 N

F= μN ( μ= Coefficient of static friction and N= max normal reaction of the car)

= 1.8 X 500g= 1.8 X 500 X 9.8= 8820 N

Alternatively known as brake power, the braking force describes the total amount of force applied to a moving body that causes it to slow down or come to a stop. Breaking force is the minimum force, expressed in pounds, at which a chain, wire cable, webbing strap, or end device breaks when a continuously increasing force is applied to it. For this force to be calculated correctly, the vehicle's body must be moving at a known, constant speed. If the car's wheels are still turning while it is braking, static friction is at work; however, if the wheels are locked and sliding over the road, kinetic friction is at work. The breaking stress or ultimate tensile stress is the highest amount of stress a material can withstand before breaking.
