Answer:
Explanation:
Here, the three components of velocity of each of the masses are provided.
The net velocity of each of three masses are:
[tex]v_{1} = \sqrt{v_{11}^{2} +v_{12}^{2} + v_{13}^{2}} = \sqrt{294} = 17.15 m/s[/tex]
Similarly,
v2 = 17.03 m/s
v3 = 52.71 m/s
Since kinetic energy is a scalar quantity, there will be no vectorial considerations involved.
[tex]KE = \frac{1}{2}m_{1}v_{1}^{2} + \frac{1}{2}m_{2}v_{2}^{2} + \frac{1}{2}m_{3}v_{3}^{2}[/tex]
Net Kinetic Energy = 4898.72 J
