13. How much power does it take to lift 30.0 kg 10.0 m high in 5.00 s?

Answer 1

Answer #1

Power is work done in unit time-

P=W/t

For lifting W=mgh

P=mgh/t

m=30kg

h=10m

t=5sec

g=9.8m/sec²

So P=30x9.8x10/5=588wattAns.

Answer 2

Answer #2

How much power does it take to lift 30.0 N 10.0 m high in 5.00 s?

> P=w/t
=300J/5sec
=60watts
