Answer : 0.4 kW
Step-by-step explanation :
Since we know that,
Power = Workdone / time
As Work done = F s
Power = ( 400 N × 60 m )/ 1 min
Here, 1 minute = 60 s
We need to keep all units in SI units.
Power = 24000 J / 60s
Power = 400 W
1 W = 1/1000 kW
= 400 × 1/1000 kW
= 0.4 kW

Answer:400W
Explanation:FORCE-400N
DISTANCE-60m
TIME -1 MINUTE OR 60 SECONDS
WORK DONE-FORCE ×Displacement
=400×60
=24000J
POWER=WORK DONE÷TIME
=24000÷60
=400W
