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
[tex]\text { Power }=\text { Force } \times \text { Velocity }[/tex]
Velocity can be calculated by dividing distance by time.
[tex]\begin{array}{l}{\text {Velocity}=\frac{\text {Distance}}{\text {Time}}} \\ {\text {Power}=\text {Force} \times \frac{\text {Distance}}{\text {Time}}}\end{array}[/tex]
So for a force of 1500 newton with distance 3 meter for a time period 50 second, power is given as,
[tex]\text { Power }=1500 \times \frac{3}{50}=150 \times \frac{3}{5}=30 \times 3 = 90[/tex]
Power = 90 watt
