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

A

`4m//s^(2)`

B

`2 m//s^(2)`

C

`8m//s^(2)`

D

`1/2m//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
The engine produces a force F on the car of mass M.
`therefore a_(1)= (F)/(M)`
When the car pulls another car of the same mass M, the total mass becomes 2M.
`therefore a_(2)= (F)/(2M) therefore a_(2) = (a_(1))/(2) = (4)/(2) = 2m//s^(2)`
