At any instant of time t, the displacement of any particle is given by 2 t - 1 (SI unit) under the influence of force of 5 N . The value of instantaneous power is (in SI unit):

Solution & Step-by-step Explanation

Displacement x = 2 t - 1 .Velocity v = \frac{d x}{d t} = \frac{d}{d t} (2 t - 1) = 2 m/s .Instantaneous power P is given by: P = F \cdot v Given F = 5 N and v = 2 m/s : P = 5 \times 2 = 10 W

Try it yourself before checking the explanation above.
