A car that has a mass of 800 kg slows down. The brakes exert a force of -2780 N. What is the acceleration of the car?

Question

Quizplus · Accepted Answer

The formula to find the required force is force = mass in kg × acceleration in m/s². F=ma To find the acceleration of an object we must isolate acceleration. To do this, we divide both sides by the mass F/m = ma/m F/m = a Then we plug in the numbers from the problem. -2780 N / 800 kg = -3.475 m/s² which rounds up to -3.5 m/s²
