Question....

Answer 1

I have to find the velocity of the centre of the mass
formula to be used
\[V^{\rightarrow}=\frac{m_{1}v_{1}^{\rightarrow}+m_{2}v_{2}^{\rightarrow}+m_{3}v_{3}^{\rightarrow}+m_{4}v_{4}^{\rightarrow}+m_{5}v_{5}^{\rightarrow}}{m_{1}+m_{2}+m_{3}+m_{4}+m_{5}}\]
But my answer is coming wrong..
Correct answer is 0.2m/s at 45 below direction towards right

Answer 2

I made a drawing but it didnt come
