Question

The engine of a car produces an acceleration of 6 ms- 2 in the car. If this car pulls another car of the same mass, then the acceleration would be, (A) 6ms- 2 (B) 12ms- 2 (C) 3ms- 2 (D) 1.5ms- 2

Let, mass of car =m . ​​​​​​Force applied by engine =6m . When two cars are pulled, (m + m)a=6m or 2ma=6m or a=3ms- 2 ,

Q. The engine of a car produces an acceleration of $6 m s^{- 2}$ in the car. If this car pulls another car of the same mass, then the acceleration would be,

$6 m s^{- 2}$

$12 m s^{- 2}$

$3 m s^{- 2}$

$1.5 m s^{- 2}$

Let, mass of car $= m$ .
Force applied by engine $= 6 m$ .
When two cars are pulled, $(m + m) a = 6 m$
or $2 ma = 6 m$ or $a = 3 m s^{- 2}$ ,

Q. The engine of a car produces an acceleration of 6ms−2 in the car. If this car pulls another car of the same mass, then the acceleration would be,

6ms−2

12ms−2

3ms−2

1.5ms−2
