Respuesta :

A wooden log is displaced to a distance of 20m in 10 seconds by applying 500N effort . Calculate the workdone and power...

Solution,

displacement = 20 m

time = 10 sec

force = 500 N

work done = ?

power = ?

Now ,

work done = f × s

= 500 N × 20 m

= 10000 j

Now ,

[tex]power \: = \frac{w}{t} \\ = \frac{10000j}{10sec} \\ = 1000W[/tex]

The work done and the power is 10000 J and 1000 W respectively.

To calculate the work done by the wooden log, we use the formula below.

Formula:

  • W = Fd............ Equation 1

Where:

  • W = Work done on the wooden log
  • F = Force applied to the wooden log
  • d = Distance traveled by the wooden log

From the question,

Given:

  • F = 500 N
  • d = 20 m

Substitute these values into equation 1

  • W = 500×20
  • W = 10000 J.

To calculate the power, we use the formula below.

  • P = W/t.............. Equation 2

Where:

  • P = Power
  • t = Time.

Given:

  • t = 10 seconds.

Substitute the values above into equation 2

  • P = 10000/10
  • P = 1000 W

Hence, the work done and the power is 10000 J and 1000 W respectively.
