A lorry and a car moving with the same kinectic energy are stopped by applying brakes which provides the same retardation. Which of them will come to a rest in a shorter distance? Explain.

The law of conversation of energy States that energy can neither be created nor be destroyed but can only change from one form into another. A bus and a car moving with the same kinetic energy are brought to rest by applying an equal ratardation force by the braking systems. Which one will come to rest at a shorter distance. Give the reason behind your answer.

The driver of a car stops his car by applying brakes to produce a uniform retardation of 8 m//s^2 , the initial speed of the car is 72 kmph.Calculate the stopping distance of the car.

A motorcycle and a bus are moving with same momentum.Which of them has greater kinetic energy?Justify.

A car of 1000kg moves with a velocity 20m//s . On applying brakes it comes to rest in 5s. What is the final momentum?

A car moving with a speed of 72 km/h comes to rest after 4s on applying brake. If the mass of the car including the passengers is 1000kg. What will be the force applied when brake is applied?
