9.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

Two balls are thrown simultaneously in air. The acceleration of the centre of mass of the two balls while in air

Two particles of different masses are thrown simultaneously in air. Centre of mass of two balls while both are in mid air.

Two balls of equal size are dropped from the same height from the roof of a building . One ball has twice the mass of the other. When the balls the ground, how do the kinetic energies of the two balls compare ?

Two balls are thrown simultaneously from top of tower in air as shown in the figure. (i) The acceleration of the center of mass of two balls while in air is equal to g . (ii) The path followed by the center of mass is parabola. (iii) The path followed by the center of mass will change if one ball after striking the ground comes to rest.

Two identical balls are set into motion simultaneously from an equal height h . While ball A is thrown horizontally with velocity v , ball B is just released to fall by itself. Choose the alternative that best represents the motion of LA and B with respect to an observer who moves with velocity v//2 with respect to the ground as shown in the figure.

Take two balls of different masses, go to the top of a building, drop them simultaneously and observe what happens to the balls.

From the top of a building , a ball is thrown horizontally. The ball strickes the ground after 5 s at an angle of 60^(@) to the horizontal. Calculate the speed with which the ball was projected .

A ball 'A' is thrown upwards from ground level with a velocity of 20 ms^(-1) . Another ball 'B' is thrown downwards from a height of 40 m with the same speed. Find the height at which the two balls meet (take g = 10 m s^(-2) ).
