Question

please help me with this

Answer 1

Explanation:

If the power of a motor is 100 kW, at what speed can it raise a load of 50,000 N? and force, F = 50000 N. Hence, the motor can lift the load with a speed of 2 ms-1.

Answer 2

Question :

If the power of a motor is 100 kW, at what speed can it raise a load of 50,000 N?

Answer:

The required speed is 2 m/s

Explanation:

The relation between power, force and velocity is given as,

 $\boxed{\sf P=Fv}$

Given,

Power = 100 kW

P = 100 × 1000 W

P = 100000 W

Force = 50,000 N

F = 50,000 N

Substituting the values,

P = Fv

100000 = 50000 × v

v = 100000/50000

v = 10/5

v = 2 m/s

Therefore, the required speed is 2 m/s
