A retarding force is applied to stop motor car. If- the speed of the motor car is doubled, how much more distance will it cover before stopping under the same retarding force?

A car and a bus start from a place P at the same time and move non-stop towards a place where the distance between P and Q is 210 km. The car takes half an hour less than the bus to arrive Q. If the average speed of the car is 10 km/h more than that of the bus, find the average speed of the car and the bus.

A constant retarding force of 50 N is applied to a body of mass 20 kg moving initially with a speed of 15 ms^-1 . How long does the body take to stop?

Speeds of two identical cars are v and 4v at a specific instant. The ratio of respective distances in which the two cars are stopped from that instant is

Draw the graphs for the following tables of values, with suitable scales on the axes. Distance travelled by a car. How much distance did the car cover during the period 7.30 a.m. to 8 a.m.?

A car is travelling at a speed of 90 km/h. Brakes are applied so as to produce a uniform acceleration of – 0.5 m/s2. Find how far the car will go before it is brought to rest?

A car moving along a straight highway with a speed of 126 km h^-1 is brought to a stop within a distance of 200 m. What is the retardation of the car (assumed uniform), and how long does it take for the car to stop?

A truck and a car with the same kinetic energy are brought to rest by the application of brakes which provide equal retarding forces. Which of them will come to rest in a shorter distance?

A horizontal force of 5000 N is required to give a 1000 kg car an acceleration of 0.20 m/sec^-2 on a level road. How large a retarding force oppse the motion.

A driver of a car travelling at 52 km h^-1 applies the brakes and accelerates uniformly in the opposite direction. The car stops in 5 s. Another driver going at 3 km h^-1 in another car applies his brakes slowly and stops in 10 s. On the same graph paper, plot the speed versus time graphs for the two cars. Which of the two cars travelle farther after the brakes were applied?

A motor car starting from rest travelled for 10 seconds with an uniform. acceleration of 5 m //s ^2 . What is the final velocity? Find the distance covered by the car.
