Two particles mass 100 g and 300 g at a given time have velocities 10 hati-7hatj-3hatk and 7hati-9hatj+6hatk ms^(-1) respectively. Detegnine yelocity of center of mass.

Two particles mass 100 g and 300 g at a given time have velocities 10

1.	Two particles mass 100 g and 300 g at a given time have velocities 10 hati-7hatj-3hatk and 7hati-9hatj+6hatk ms^(-1) respectively. Detegnine yelocity of center of mass.
Answer» Solution :VELOCITY of center of MASS`=(31i-34j+15k)/(2)ms^(-1)`
