Question

A force if 7i+6j N make a body move on rough plane with a velocity of 3j+4k m/sec. calculate the power

Answer 1

Answer:

18 j

Explanation:

see. we have to do simple dot product here.

P = F.V = (7i + 6j +0k).(0i + 3j+4k) = (7*0)i +(6*3) j+ (0*4)k. = 18 j

Thanks. I hope you will understand.
