To find the instantaneous power, we need to determine the velocity and then use the formula for power.$\\$Given:$\\$• Displacement $x(t) = 2t - 1$ (SI unit)$\\$• Force $F = 5$ N$\\$First, find the velocity $v(t): \\ v(t) = \frac{dx}{dt} = \frac{d}{dt}(2t - 1) \\ v(t) = 2 \\$The velocity is constant and equal to 2 m/s.$\\$Instantaneous power $P$ is given by:$\\ P = F \cdot v \\$Substitute the known values:$\\ P = 5 \cdot 2 \\ P = 10$ W$\\$Therefore, the value of instantaneous power is $10$ W. This corresponds to Option 3.
