Question

A force of 6 N produces an acceleration of 12 m/s2 on an object of mass m1 and an
acceleration of 24 m/s2 on an object of mass m2. What will be the acceleration produced,
if the two objects are tied up and the same force acts on them?

Answer 1

Answer:

a = 8 $m$/$s^{2}$

Explanation:

F = ma

1.)  6 = $m_{1}$ x 12

    $m_{1}$ = 1/2

2.) 6 = $m_{2}$ x 24

    $m_{2}$ = 1/4

Now, if both are tied together: m = $m_{1}$ + $m_{2}$ = 1/2 + 1/4 = 3/4

F = ma

6 = 3/4 x a

a = 8 $m$/$s^{2}$

Hope it helps!
