Question

A force of 5N gives a mass of m1, an acceleration of 10m/s2 & a mass m2, an acceleration of 20m/s2.What acceleration would it give if both the masses were tied together?

Answer 1

Answer:

(5×4/3) m/s2.

Explanation:

when both of them are tied together then total mass is M1+M2.so on calculation from the expression f=m/a we get M1 =1/2 and M2 =1/4.so M1+M2 is 3/4. therefore total acceleration of the system is (5×4/3) m/s2.
