Power (P) is defined as the rate at which work is done or energy is transferred. The formula to calculate power is: P = W / t Where: W = work done (in Joules) t = time (in seconds) First, we need to calculate the work done (W) by multiplying the force (F) by the displacement (d): W = F × d = 2.0 N × 1.0 m ( converted 100 cm to 1.0 m) = 2.0 J Now, we can calculate the power output (P) by dividing the work done (W) by the time (t): P = W / t = 2.0 J / 4 s = 0.5 W So, the power output of the motor is 0.5 W.
An electric motor is used to lift the weight of 2.0N through a vertical distance of 100 cm in 4 sec. What is the power output of the motor?
