Question

the power of a motor is 40kw. at what speed can the motor raise a load of 20000N

Answer 1

p=fv =40000v=20000n v=40000/20000=2m/s

Answer 2

Power = 40kwh

Change it in W

= 40 × 10^3

= 40,000 W

Force = 20,000 N

Using Formula

P = Fv

$\textbf => \dfrac{P}{F} = v$

$\textbf => \dfrac{40,000}{20,000} = v$

= 2 m/s
