1. The problem statement, all variables and given/known data Find the power input of a force vector F acting on a particle that moves with a velocity vector v for each of the following situations. (a) vector F = 4 N i hat + 3 N k hat , vector v = 9 m/s i hat 2. Relevant equations P = F * V 3. The attempt at a solution P =(4*9) +3 Also tried P = SQRT(4^2+3^2) * 9 I guess the problem is I don't know how to convert the vector 4i+3j into a force.
