Part 1

A train starting from rest accelerates uniformly for 100 s, then comes to a stop with a uniform retardation in the next 200 s. During the motion, it covers a distance of 3 km. Choose the wrong option A train starting from rest accelerates uniformly for 100 s it covers a distance of 3 km. [...]

The engine of a motorcycle can produce a maximum acceleration of 5 m/s^2. Its breaks can produce a maximum retardation 10 m/s^2. What is the time in which the motorcycle can cover a distance of 1.5 km ? A particle starts its motion from rest under the action of a constant force. If the distance [...]

A car accelerates from rest at a constant rate α for some time after which it decelerates at a constant rate β to come to rest. If the total time elapsed is t, then the maximum velocity attained is A car accelerates from rest at a constant rate α for some time after which it [...]

A body A starts from rest with an acceleration a1​. After 2 seconds, another body B starts from rest with an acceleration a2​. If they travel equal distances in the 5th second, after the start of A, then the ratio a1​ : a2​ is equal to A body A starts from rest with an acceleration [...]

A man is d distance behind the bus when the bus starts accelerating from rest with an acceleration a0. With what minimum constant velocity should the man start running to catch the bus A man is d distance behind the bus when the bus starts accelerating from rest with an acceleration a0. With what minimum [...]

A cyclist starts from rest and moves with a constant acceleration of 1 m/s^2. A boy who is 48 m behind the cyclist starts moving with a constant velocity of 10m/s. After how much time the boy meets the cyclist? A particle starts its motion from rest under the action of a constant force. If [...]

Two trains travelling on the same track are approaching each other with equal speed of 40m/s. The drivers of the trains begin to decelerate simultaneously when just ` 2.0 km apart. Assuming deceleration to be uniform and equal the value to the deceleration to barely avoid collision should be . A particle starts its motion [...]

Two cars A and B are at rest at the origin O. If A starts with a uniform velocity of 20m/s and B starts in the same direction with a constant acceleration of 2m/s^2 , then the cars will meet after time then the cars will meet after time Two cars A and B are [...]

Speeds of two identical cars are u and 4u at a specific instant. The ratio of the respective distances in which the two cars are stopped at the same instant is Speeds of two identical cars are u and 4u at a specific instant. The ratio of the respective distances in which the two cars [...]

A body moving with a uniform acceleration crosses a distance of 15 m in the 3rd second and 23 m in the 5th second. The displacement in 10 s will be A body moving with a uniform acceleration crosses a distance of 15 m in the 3rd second and 23 m in the 5th second. [...]
