Question

the engine of a car produce acceleration 4m/s2 in the car. if this car pulls another car of same mass. what will be the acceleration produced -

Answer 1

The engine of a car produce acceleration 4m/s^2 in the car.

If this car pulls another car of same mass, then the mass is doubled.
But the force remains same.

We know that F=ma.
So acceleration will be halved i.e. acceleration will be 2 m/s^2.

Answer 2

Answer:

2m/s

Explanation:

as f=ma

force on car 1 will be 4m

so for whole body

F=2m a

4m = 2ma

so a = 2m/s
