Question

two bodies having masses m1 =10kg nd m2=1kg respectively are falling freely from height h=20m.cmpare their I0inertiaii)their final velocity jst before hitting the ground(clearly state ur assumption)

Answer 1

m1=10kg and m2=1 kg
(i)
Since inertia is a measure of mass,
So the ratio of the inertia for bodies=10:1
(ii)
Galileo’s experiment proves that two objects of same or different mass when dropped from same height with same initial velocity will reach the ground at the same time and with same velocity.
$$\begin{gathered} v^2=u^2+2gh \\ =0+2\times 10\times 20 \\ v=20m/s \end{gathered}$$
So,
v1=v2=v
or v1:v2=1:1
