Question

An object of 30 kg mass takes 1 minute to lift up to 2 meters. Calculate the power consumed.

Answer 1

Answer:

1 minute=60 seconds

So P=W/t=mgh/t

=30*9.8*2/60

=9.8 J

Answer 2

Answer:

Answer :

Mass (m) = 30kg

Distance (s) = 2 m

Time (t) = 1minute = 60 seconds

P = 10 Watt

Hence, the power consumed is 10 wattts
