Question

Two balls of equal mass pre projected
& vertically upwards simultanesouly one
from the ground with initial velocity
soms and the other from your
tower with an intial velocity of
zomrs. The mostmum height of
their centre of mass from the
ground is​

Answer 1

Hey buddy here's your answer

Initially the center of mass, COM, will be at a height of 20 m from the ground.

Since both are of same mass and are at a distance of 40 m from each other.

The speed of COM will be 250+30=40 m/s

∴ the maximum height reached by the COM is

20+uc square ÷2g=20+40*40÷2*10

=100m .

I hope this will help you
