Question

A cyclist overcomes a resistive force of 30N in order to cycle 30m. It takes her 6 seconds to cycle this distance. calculate the power of the cycist

Answer 1

Answer

• Power of the cyclist = 150 Watt.

Given

• A cyclist overcomes a resistive force of 30N in order to cycle 30m. It takes her 6 seconds to cycle this distance.

To Find

• The power of the cyclist.

Step By Step Explanation

Given that ⤵

• Force = 30 newton.

• Distance = 30 meters.

• Time = 6 seconds.

We need to find the power of the cyclist.

So, Let's do it !!

$\pink\maltese \boxed{\bf{\purple{Work =Force \times Distance }}}$

By substituting the values

$\longmapsto \sf \: Work = 30 \times 30 \\ \\\longmapsto \bf Work = 900 \: Joule$

$\green\maltese \boxed{\bf{\red{Power = \cfrac{Work}{Time}}}}$

By substituting the values

$\longmapsto \sf \: Power = \cancel\cfrac{900}{6} \\ \\\longmapsto \bf Power = 150 \: Watt$

Therefore power of the cyclist = 150 Watt.

Answer:

• 150 Watt

Explanation:

Given:

• A cyclist overcomes a resistive force of 30N in order to cycle 30m. It takes her 6 seconds to cycle this distance.

ToFind:

• Calculate the power of the cycist

Calculation:

>> work = force*distance

>> work = 30*30

>> work = 900j

>> power = work/time

>> power = 900/6

>> power = 150watt
