A CAR TRAVELLING AT 36 KM/H IN 5 SECONDS.WHAT IS THE ACCELERATION.? IF THE SAME CAR STOPS IN 20 SECONDS , WHAT IS THE RETARDATION ?

Q. A car is travelling with a speed of 36km/h. The driver applies brakes retards the car uniformly. The car is stopped in 5seconds. Find the retardation of the car and the distance travelled before it is stopped.

Q. A car moving with a velocity of $20{ms}^{-1}$ is stopped in a distance of $40m$. If the same car is travelling at double the velocity, the distance travelled by it for same retardation is

Q. A car is travelling along a circular curve that has a radius of $50\text{m}$ with a constant tangential acceleration. If the speed of the car changes from $36\text{km/hr}$ to $45\text{km/hr}$ in $5\text{seconds}$, the angular acceleration of the car is.(No slipping between road and car tyre)

Q. Question 5
A driver of a car travelling at 52 kmph applies the brakes and accelerates uniformly in the opposite direction. The car stops in 5 seconds. Another driver going at 3 kmph in another car applies his brakes slowly and stops in 10 seconds. On the same graph paper, plot the speed versus time graphs for the two cars. Which of the two cars travelled farther after the brakes were applied?
