Answer:
[tex]P=7.35\times 10^{3}\ W[/tex]
Explanation:
Given that,
Mass, [tex]m=1.5\times 10^2\ kg[/tex]
It lifts to a height of 15 m in 3 s
We need to find the power of the motor. The formula for power is given by :
[tex]P=\dfrac{W}{t}\\\\P=\dfrac{mgh}{t}\\\\P=\dfrac{1.5\times 10^2\times 9.8\times 15}{3}\\\\P=7.35\times 10^{3}\ W[/tex]
So, the power of the motor is equal to [tex]7.35\times 10^{3}\ W[/tex].
