P=-60W

Explanation:

From the question we are told that

Force of power F=8Ni+-4Nj

Velocity of power V=-7m/si+1m/sj

Generally the equation for power is mathematically represented as

Power=Force *Velocity

P=F *V

Generally the dot product of F and V is mathematically given as

$\begin{vmatrix}8 & -4\end{vmatrix} .$ $\begin{vmatrix}-7 & 1\end{vmatrix}$ =-56-4

P=-60W
