You are movingto a new apartment. It takes you 2 seconds to lift a 200 N box and move it 1.5 meters. How much power did you exert? W = Fd and P=W/t\
400 W

150 W

300 W

600 W

We know that work is a product of force and distance, expressed as [tex]W=Fd[/tex] where W -work in Nm or Joules, F is exerted force in Newtons and [tex]d[/tex] is the perpendicular distance moved in meters. Substituting F with 200 N and d with 1.5 m then work will be W= 200*1.5= 300 Nm= 300

Since power is defined as rate of work per unit time then power

[tex]P=\frac{W}{T}, W=300J,T=2\\\\P=\frac{300}{2}\\\\=150W[/tex]

Hence, the power exerted is 150W
