Question

A bus and a car are moving on a horizontal road with the same
kinetic energy. These are brought to rest by the application of brakes which provided equal retarding forces. Which of these will come to rest in shorter distance?
​

Answer 1

ANSWER:

The car

EXPLANATION:

If a car has mass and velocity then it will definitely have momentum (which can be written as mass X velocity). Since larger mass gives greater momentum, it will take a larger force to stop a heavy massed object. Therefore, assuming that the car has a smaller mass compared to that of the bus, it will take a shorter force for the car to stop, and a larger force for the bus to stop.

Answer 2

Answer:

Car because it's mass is less than the bus so it will comes first to rest.
