Question

A mass of 210 kg is moved upward a vertical distance of 60 m in a time of 2 minutes.: The power required to lift this mass is equal

Answer 1

A mass of 210 kg is moved upward a vertical distance of 60 m in a time of 2 minutes.:The power required to lift this mass is equal

The correct answer: P= 1029 N

:The explanation

P= force×velocity= F×v

F= m×a= 210×9.80=2058 N

v= distance/time 

Convert time from minutes to second 2×60 = 120 second

v= 60/120=0.5 m/s

P= 2058×0.5= 1029 W
