Velocity of a particle at some instant is `v=(3hat i + 4hat j + 5hat k) m//s`. Find speed of the particle at this instant.

A force 3hat i+4 hat j - 5 hatk N is acting on a particle. If the velocity of particle at an instant is 2hati + 2 hat j + 2 hatk m/s , find the instantaneous power developed by the force (in watts).
