W = K.E = 6.4 kJ = 6.4 x 103 J W = F.d. cos θ Now the displacement of the body is in the direction of applied force. θ = 0 W = F.d F = W/d = (6.4 x 103 J)/64 m F = 100 N Power P = W/t = (6.4 x 103 J)/(2.5) =16 x 103 W =1.6 x 104 W = (1.6 x 104) / 746 = 0.0021 x 104 H.P. Power P = 21 H.P.

Yo, wassup?

I'm confused. Shouldn't the F be 10.3?

Work = Force x Displacement and this work done will be equal to energy supplied, Right?
AaronAndyson
  • AaronAndyson
Yes.

  • Abhisar
Let the applied force be F, then 6400 = F x 64. Now you can calculate the force.

And the P?

\(\sf Power = \frac{Work/Energy}{Time}\) You know the work, you know the time. Just plug in the values and find power.

6.4 KJ = 6400 J

Power = 6400/25

Time is 2.5 s not 25s
Abhisar
  • Abhisar
Right, then it's correct!

Finally, convert the power into HP. 1 HP =746 Watts.
