Given :
One particle, of mass m , moves with a speed v in the x-direction, and another particle, of mass 2 m , moves with a speed v/2 in the y-direction.
To Find :
The velocity of the center of mass of these two particles.
Solution :
Speed of mass m, .
Speed of mass 2m , .
Speed of center of mass is given by :
Hence, this is the required solution.
Equation: E = m(c^2)
c = 3*(10^8)m/s
m = 5.0 kg
E = 5.0kg * [3*10^8 m/s]^2 = 45*10^16 joule = 4.5*10^17 joule
Answer: 4.5*10^17 joule
Answer:602.27 kg
