A crane lifts a mass of 100 kg to a height of 10 m in .20 s. The power of the crane is (Take g = 10 m s-2)

Question

A crane lifts a mass of 100 kg to a height of 10 m in .20 s. The power of the crane is (Take g = 10 m s-2) (A) 100 W (B) 200 W (C) 250 W (D) 500 W

Tardigrade Admin · Accepted Answer

Here, m=100 kg h=10 m , t=20 s , g=10 ms -2 g=10 ms -2 The power of the crane is P=(m g h/t) =((100 kg )(10 ms -2)(10 m )/(20 s )) =500 W

Q. A crane lifts a mass of $100 k g$ to a height of $10 m$ in . $20 s$ . The power of the crane is (Take $g = 10 m s^{- 2}$ )
