Question

The power of the crane was 68600w Caculate the time taken for the crane to do 3430000 J of work Give the unit

Answer 1

`T \approx 5s`

Step-by-step explanation:

From the question we are told that:

Power
`P=686600w Js^(-1)`

Work
`W=3430000 J`

Generally the equation for Time t is mathematically given by

`T=(Work)/(Power)`

`T=(W)/(P)`

Therefore

`T=(3430000 )/(686600)`

`T=4.996`

`T \approx 5 s`
