The driver of a truck travelling with a velocity upsilon suddenly notices a brick wall in front of him at a distance d It is better for him to apply brakes or to make a circular turn without applying brakes in order to just avoid crashing into the wall ? Why ?

The driver of a car travelling at velocity v suddenly see a broad wall in front of him at a distance d. He should

The dirver of a car travelling at a velcituy (v) suddenly sees a broad wall in front of mim at a distance r . Is it better to brake or to turn sharply ?

The driver of a car travelling with velocity v on a road suddenly sees a broad wall in front of him at a distance r . He has two alternatives: to turn sharply or a brake instantly. The passenger who is a professor of physics, advises him to brake to avoid collision. Read the above passage and answer the following questions: (i) How is the suggestion from Professor of Physics justified? (ii)Does the suggestion work really? (iii)What value do you learn from this experience?

The driver of a bus travelling with a speed 'v' suddenly observes a wall in front of his bus at a distance 'a'. Father of this driver, who was also a driver, had advised him to take circular turn to avoid hitting in such a situation. However, the driver in question decides otherwise by using his own wisdom. He applies brakes as hard as possible without taking a circular turn, then :

The driver of a car-travelling at speed V suddenly sees a wall at a distance r directly infront of him. To avoid collision. He should :

The driver of a car travelling at speed v suddenly sees a wall at a distance r directly infront of him. To avoid collision, should he apply the brakes or turn the car sharply away from the wall ? Give reason.

A car driver going at speed v suddenly finds a wide wall at a distance r . Should he apply breakes or turn the car in a circle of radius r to avoid hitting the wall.

The driver of a train travelling at 115 km/hour sees on the same track 100 m in front of him a slow train travelling in same direction at 25 km/hr. The least retardation that must be applied to the faster train to avoid a collision will be-

Statement I: The driver of a moving car sees a wall in front of him. To avoid collision, he should apply brakes rather than taking a turn away from the wall. Statement II: Frictional force is needed to stop the car or taking a turn on a horizontal road.

A car is moving with a velocity of 10 m/s. Suddenly driver sees a child at a distance of 30 m and he applies the brakes, it produced a uniform retardation in car and car stops in 5 second. Find (mass of car=1000 kg) the stopping distance of car will the car hit the child the retardation in car resistive force on car
