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?

You are driving a motorcycle ona horizontal raod. It is moving with a uniform velocity. Is it possibel to accelerate the motorcycle wilthout putting higher petrol input rate into the engine?

The angular velocity of the engine (and hence of the wheel) on a scooter is proportional to the petrol input per second. The scooter is moving on a frictionless road with uniform velocity. If the petrol input is increased by 10% the linear velocity of the scooter is increased by

Incomplete combustion of petrol or diesel in automobile engine produces

A rail road car of mass M is at rest on frictionless rails when a man of mass m starts moving on the car towards the engine. If the car recoils with a speed v backward on the rails, with what velocity is the man aproaching the engine?

A car can pull a trailer of twice its mass up a certain slope at a maximum speed v=1m//s . Without the trailer the maximum speed of the car up the same slope is 2v . The resistance to the motion is proportinal to mass and square of speed. If the car (without trailer) starts to move down the same slope, with its engine shut off, eventually it will acquire a constant speed v_(t) , then find v_(t)^(2) (in m^(2)//s^(2) )

To accelerate a car we ignite petrol in the engine of the car. Since only an external force can accelerate the centre of mass, is it proper to sasy that the fore generated by the engine accelerates the car?

In internal combustion petrol/diesel engines, only cyclic processes are used, because:

The engine of a car produces acceleration 4m//s^(2) in the car. If this car pulls another car of same mass, what will be the acceleration produced
