When a train starting from rest is uniformly accelerating, a plumb bob hanging from the roof of a compartment is found to be inclined at an angle of `45^(@)` with the vertical.The time taken by the train to travel a distance of `1//2km` will be nearly

A plumb line is hanging from the roof of a car. When the car moves with an acceleration a, the angle that the plumb line makes with the vertical is

A plumb bob is hanging from the ceiling of car. If the car move with acceleration a, the angle made by the string with the vertical is

A body is suspended from the roof of a train by a string. What angle is formed by the string with the vertical, when the train moves at a constant acceleration of a ?

A train starting from rest moves with a uniform acceleration of 0.2 m//s^(2) for 5 minutes . Calculate the speed acquired and the distance travelled in this time.

A motorcycle starts from rest. The uniformly accelerates at 1m//s^2 . Find the distance travelled in the 3rd second.

A train starting from rest attains a velocity of 72 km/h in 5 minutes. Assuming that the acceleration is uniform Find the acceleration.

The brakes of a train which is travelling at 30 m//s are applied as the train passes point A. The brakes produce a constant retardation of magnitude 3lambda m//s^(2) until the speed of the train is reduced to 10 m//s . The train travels at this speed for a distance and is then uniformly accelerated at lambda m//s^(2) until it again reaches a speed of 30 m//s as it passes point B. the time taken by the train in travelling from A to B, a distance of 4 km, is 4 min. Sketch the speed time graph for this motion and calculate:- (i) The value of lambda (ii) Distance travelled at 10 m//s .

A train starte from rest and moves with a constant acceleration of 2ms^(-2) for half a minute. The brakes are then applied and the train comes to rest in one minute.find (i) the maximum speed attained by the train (ii) the total distance moves by the train and (ii) the positions (s) of the train a half the maximum speed.
