Question

if the power of moter is 40kilo watt at what speed can it rise the load of 20,000newton??send me fast​

Answer 1

Solution :

⏭ Given:

✏ Power of moter = 40,000 watt

✏ Weight Force = 20,000 N

⏭ To Find:

✏ Speed of the load

⏭ Formula:

✏ Relation between power, force and speed is given by

$\bigstar \: \boxed{ \bold{ \sf{ \large \pink{P = F \times v}}}} \: \bigstar$

⏭ Terms indications:

✏ P denotes power

✏ F denotes force

✏ v denotes speed

⏭ Calculation:

$\mapsto \sf \: v = \dfrac{P}{F} \\ \\ \mapsto \sf \: v = \dfrac{4 \cancel{0000}}{2 \cancel{0000} } \\ \\ \mapsto \: \boxed{ \red{ \sf{ \large{v = 2 \: mps}}}} \: \gray{ \bigstar}$

Answer 2

$\huge{ \mathtt{ \fbox{Solution :) }}}$

Given ,

Power = 40 kilo watt or 40000 watt

Force = 20000 newton

We know that , the rate of work done is called power

$\star \: \sf Power = \frac{work}{time} \\ \\ \star \:\sf Power = \frac{force \times displacement}{time} \\ \\ \star \: \sf Power = force \times velocity$

Thus ,

40000 = 20000 × velocity

velocity = 40000/20000

velocity = 2 m/s

Hence , the velocity is 2 m/s
