Two point masses connected by an ideal string are placed on a smooth horizontal surface as shown in the diagram. A sharp impulse of $10 k g m s^{- 1}$ is given to the $5 k g$ mass at an angle of $60 °$ to the line joining the masses. The velocity of the $10 k g$ mass just after the impulse will be

Question

Two point masses connected by an ideal string are placed on a smooth horizontal surface as shown in the diagram. A sharp impulse of

10 k g m s^{- 1}

is given to the

5 k g

mass at an angle of

60 °

to the line joining the masses. The velocity of the

10 k g

mass just after the impulse will be
