An automobile vehicle has a mass of . What must be the force between the vehicle and the road if the vehicle is to be stopped with a negative acceleration of ?
Step 1: Given data:
In the question, it is given that the mass of an automobile is which is deaccelerating with the acceleration of .
So, and
Step 2: Formula used:
We know that the formula of force is mass multiplied by acceleration, i.e. .
Step 3: Find the required force:
Therefore, the force between the vehicle and the road is given by:
The negative sign implies that the force is in the opposite direction of motion.
Therefore, the force between the vehicle and the road is .
