You are driving a motorcycle on a horizontal road. It is moving with a uniform velocity. Is it possible to accelerate the motorcycle without putting higher petrol input rate into the engine?

The increase in the speed of a car is proportional to the additional petrol put into the engine. Is it possible to accelerate a car without putting more petrol or less petrol into the engine?

A car is moving with uniform velocity on a rough horizontal road. Therefore, according to Newton's first law of motion

An open carriage in a goods train is moving with a uniform velocity of 10 m/s. If the rain adds water with zero velocity at the rate of 5 kg/s, then the additional force required by the engine to maintain the same velocity of the train is

A circular disc rolls on a horizontal floor without slipping and the center of the disc moves with a uniform velocity v. Which of the following values of the velocity at a point on the rim of the disc can have?

Assume that a car is moving behind a loaded truck. Both moving with the same uniform velocity. A box from the top of the truck falls. Does car hit the box before the box hits the road, if driver neither brake nor accelerate ?

The speed a motorcycle moving along a circular road of radius 300 m, is increasing at the rate of 4 m//s^(2) . Calculating the acceleration of the motorycle when its speed is 30 m/s

Two cars A and B of equal masses (100 Kg) are moving on a straight horizontal road with same velocity 3m//s as shown. At t = 0 car A starts accelerating with constant acceleration of 2 m//s^(2) (intial separation between car is 25 m ). Choose correct options (neglect length of cars)

A lift is moving downwards. A body of mass 2 kg kept on the floor is pulled horizontally and is in motion. If the coefficient of friction between the body and floor is 1 // 2 , find the friction acting on the body if (a) lift is moving with a uniform velocity and (b) lift is moving with acceleration 5 m//s^(2) in the downward direction.

A uniform disc of mass 1 kg and radius 20 cm is rolling purely on a flat horizontal surface. Its centre C is moving with acceleration a = 20 ms^(-2) and velocity v =4 m//s at a certain instant. At this instant. points A and B are located on the disc as shown in the diagram, with AC = BC = 10 cm . What is the acceleration magnitude of point A ?
