A force of 50N produces an acceleration of 10m/s2on a body of mass m1 and an acceleration of 20m/s2 on a body of mass m2. Find the acceleration produced by the same force if both the bodies were tied together.
A force of 5 N gives a mass m1 an acceleration of 8ms−2 and a mass m2 an acceleration of 24 ms−2. What acceleration would it give if both the masses are tied together?
In making an alloy , a substance of specific gravity s1 and mass m1 is mixed with another substance of specific gravity s2 and mass m2 ; then the specific gravity of the alloy is
