Question

The engine of a car produces an acceleration of 6m/s square in the car. if the car pulls a block of the same mass then the acceleration woul?

Answer 1

ANSWER
.....

..

whatever be the mass of the car the force applied


since F = m *a

we get F = m * 6 => m = F/6. 

now if a block of mass 'm'. Therefore mass the engine has to pull = 2m


since force applied by engine is constant F =

(2m)*A (A is the new acceleration) 


now we put value of m (F/6) in this equation

and we get F = 2(F/6)*A 


on solving A = 3 m/s².

Answer 2

Answer:3

Step-by-step explanation:

let acceleration of car is a

F=ma

F=2ma'

a=2a'

a'=a/2

=6/2

=3m/s2
