Question

a particle of mass m is thrown horizontally from the top of a tower
and another particle of mass 2m is thrown vertically upward the
accln of centre of mass is ?
1 g
2 9g/3
3 2g/3
4 g/2

Vara · Accepted Answer

Acceleration of both particles is same, which is equal to the
acceleration due to gravity

Mass and Acceleration of each particle:

m1=m  and m2=2ma1=g  and a2=gAcceleration of centre of mass:acm=m1a1+m2a2m1+m2       =mg+2mgm+2m        =3mg3m        =gAns: Option - (1)
