A 5.8x10 ^4 watt elevator motor can lift a total weight of 2.1 x10^4 newtons with a maximum constant speed of
The formula for power is used to solve for the speed. Given are P = 5.8x10^4 W and W = 2.1 x10^4 N = F. Formula: v =P / F this would result to v = 5.8 x10^4 W / 2.1x10^4 N = 2.76 m/s. I hope this helps you
Answer : The speed of motor will be, 2.76 m/s
Solution : Given,
Power of motor = \(5.8\times 10^4watt\)
Force = \(2.1\times 10^4N\)
Formula used :
\(Power=Force\times Velocity\\\\Velocity=\frac{Power}{Force}\)
Now put all the given values in this formula, we get the speed of motor.
\(Velocity=\frac{Power}{Force}=\frac{5.8\times 10^4watt}{2.1\times 10^4N}=2.76m/s\)
Therefore, the speed of motor will be, 2.76 m/s
