Question : 25
Total: 76
Calculate the power spent by a crane while lifting a load of mass 2000 kg 1.5 ms − 1 ⋅ ( g = 10 ms − 2 )
Solution:
Given : m = 2000 kg , v = 1.5 ms − 1
g = 10 ms − 2 , P = ?
We know,
Power ( P ) =
=
( ∵ W = m g h )
= m g × v ( ∵
= v )
= 2000 × 10 × 1.5 watt
= 30 , 000 watt
We know,
