The distance required for a car to come to a stop will vary depending on how fast the car is moving. suppose that a certain car traveling down the road at a speed of 10 m / s can come to a complete stop within a distance of 20 m . assuming the road conditions remain the same, what would be the stopping distance required for the same car if it were moving at speeds of 5 m / s , 20 m / s , or 40 m / s ?

5 m

80 m

320 m

Explanation:

= Initial speed of the car = 10 ms⁻¹

= Final speed of the car = 0 ms⁻¹

= Stopping distance of the car = 20 m

= acceleration of the car

On the basis of above data, we can use the kinematics equation

= Initial speed of the car = 5 ms⁻¹

= Final speed of the car = 0 ms⁻¹

= Stopping distance of the car

= acceleration of the car = - 2.5 ms⁻²

On the basis of above data, we can use the kinematics equation

= Initial speed of the car = 20 ms⁻¹

= Final speed of the car = 0 ms⁻¹

= Stopping distance of the car

= acceleration of the car = - 2.5 ms⁻²

On the basis of above data, we can use the kinematics equation

= Initial speed of the car = 40 ms⁻¹

= Final speed of the car = 0 ms⁻¹

= Stopping distance of the car

= acceleration of the car = - 2.5 ms⁻²

On the basis of above data, we can use the kinematics equation

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.
