A box is pushed across 10m by a force of 40 N in 10 seconds.calculate the power.​
alexandr402 [8]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{40 \: watt}}}}}

Explanation:

Given,

Distance ( D ) = 10 m

Force ( F ) = 40 N

Time taken ( T ) = 10 seconds

<u>Calculating </u><u>the </u><u>power:</u>

\boxed{ \sf{power =  \frac{work}{time} }}

⇒\sf{power =  \frac{force \times distance}{time} }

⇒\sf{power =  \frac{40 \times 10}{10} }

⇒\sf{power =  \frac{400}{10} }

⇒\sf{power = 40 \: watt}

Hope I helped!

Best regards!!
