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

Options

A. is equal to g (Acceleration due to gravity)
B. depends on the masses of the two balls
C. depends on the direction of motion of the two balls.
D. depends on the speeds of the two balls.

Answer

A

Explanation

When two balls are thrown simultaneously in air, they will follow parabolic path and the force acting on the system is the gravitational pull.
`:.` The force on centre of mass is the force due to gravity. This implies that the acceleration of the centre of mass is equal to the acceleration due to gravity.
