Question

2. A force of 500 N acts on a body of mass x and gives it an acceleration of 200 m/s2. The same
force acting on another body of mass y gives it an acceleration of 40 m/s2. If x and y are
tied together and the same force as above, acts on them, what acceleration is produced in the
combination?
​

Answer 1

Explanation:

$(x)f = ma \\ 500 = m \times 200 \\ m = 2.5kg \\(y) f = ma \\ 500 = 40m \\ m = 12.5kg$

we found the masses then let's apply f=ma to the system

$f = ma \\ 500 = 15a \\ a = 33.33m {s}^{ - 2}$
