1. The problem statement, all variables and given/known data An object moving with a velocity whose components are [4m/s,-1m/s,3m/s] is acted on by a force whose components are [-5N,0,+5N]. What is the power of the energy transfer involved in this interaction? 2. Relevant equations Power=F*v 3. The attempt at a solution 4m/s*-5N= -20W -1m/s*0=0W 23m/s*5N=15W (202+152+02)sqrt=Magnitude = 25W which could be the answer but I'm not sure. I just dont know how negative velocity affects power because P=Fv so if F is 5N and v=-3m/s then it would seem like -15W is the answer but im not sure. I also don't really have experience with 3-component vectors.
