Question

A force of 5N gives a mass m1 an acceleration of 10ms-2 and a mass m2 an acceleration of 20ms-2. What acceleration would it give if both the masses were tied together?

Answer 1

F = m x a
5=m1 x 10
m1=5/10=0.5
similarly, m2=5/20=0.4
now,m1 + m2 =0.5 + 0.4 = 0.9
then, acceleration = F/M = 5/0.9 = 50/9 = 5.55 ms^-2
