Question

An elevated weighing 15,00 Newton’s is raised one story in 50 seconds. If the distance stories is 3.0 meters how much power is required of the motor

Answer 1

Power required for motor to raise elevated weighing 1500 newton for a distance of 3 meter in 50 second is 90 watt.

Solution:

By using power force formula,

Power is obtained by multiplying force and velocity

`\text { Power }=\text { Force } * \text { Velocity }`

Velocity can be calculated by dividing distance by time.

`\begin{array}{l}{\text {Velocity}=\frac{\text {Distance}}{\text {Time}}} \\ {\text {Power}=\text {Force} * \frac{\text {Distance}}{\text {Time}}}\end{array}`

So for a force of 1500 newton with distance 3 meter for a time period 50 second, power is given as,

`\text { Power }=1500 * (3)/(50)=150 * (3)/(5)=30 * 3 = 90`

Power = 90 watt
