Question

Two balls are thrown in air. The second ball is thrown 2 seconds after the first ball. The acceleration of the center of mass of the two balls while in air : (A) Depends on the direction of the motion of the balls (B) Depends on the masses of the balls (C) Depends on the speed of two balls (D) is equal to 'g'

aC M=(f textnet /m)=(m g + m g/2 m)=g

Q. Two balls are thrown in air. The second ball is thrown $2$ seconds after the first ball. The acceleration of the center of mass of the two balls while in air :

Depends on the direction of the motion of the balls

Depends on the masses of the balls

Depends on the speed of two balls

is equal to $^{'} g^{'}$

$a_{CM} = \frac{f _{net}}{m} = \frac{m g + m g}{2 m} = g$
