Question

A car speeds up while the engine delivers constant power. Is the acceleration greater at the beginning of this process or at the end? Explain.

Answer 1

The acceleration greater at the beginning of this process

Step-by-step explanation:

The car when starting to move is necessary an acceleration therefore at the beginning of the movement there is an acceleration. The engine power is at a constant value so that when the car reaches the maximum speed (constant speed) at that power there will be no acceleration.

That is to say, at constant speed = zero acceleration

And of course this final null acceleration will be less than the initial acceleration so that the car starts to move .
