Question

A Body of mass m is dropped from the top of tower during the first second it will fall through ​

Answer 1

Explanation:

Initial velocity U, of center of mass of two masses in motion is

(M+m)

(Mu+mu

1

)

.

The initial velocity for mass m is zero, hence u

1

is zero.

We are calculating the maximum height above the height of tower H,

Hence we add the maximum height attained by this system to the height of towerH.

WHich is H+
