Question

Two identical balls are thrown obliquely from the ground simultaneously. The acceleration of centre of mass


(A)does not depend on the mass of the two balls
(B) depends on the direction in which two balls are projected
(C) is equal to g
(D) is zero​

Answer 1

Since there is no force in the horizontal direction there will be no acceleration of CoM in the horizontal direction whatever be the direction, mass or speed of the two balls. Only force is the gravitational force hence acceleration of CoM will be acceleration due to gravity g.

Answer 2

Answer:

c . Acceleration is 0i -gj

ball shall follow the equation of motion of a projectile in 2D and is Parabolic
