Crane A has 2.0 as much power as Crane B.

If Crane B can do 9492 Joules of work in 12.492 minutes, how many Joules of work can Crane A do in 12.492 minutes?

  • Physics -

    Does crane A and B have anything in common?

  • Physics -

    They are both using rope and pulley systems to lift a load from a truck to the top of a building

  • Physics -

    something is missing.

  • Physics -

    that's all that was given in the problem

  • Physics -

    P(A) = W(A)/t = 9492/12.492•60 = 12.66 W
    P(B) = P(A)/2 = 6.33 W
    W(B) = P(B) •t = 6.33•12.492•60 = 4946 W
