Question

A 60kg person climb stairs of total length 20 metre in 2 minutes .calculate the power delivered

thank you​

Answer 1

Explanation:

let assume,

m=60kg.

h=20m.

t=2min.

g=10m/s²

p. e=mgh

p. e=60×20×10

p. e=1200joules.

hence,

we know that

(p. e =w)

p=w/t

p=1200/2

p=600W.

THANKS ♥.

Answer 2

Answer:

GIVEN -

M=60kg

L=20m

T=120 sec.

We know

P. E=mGh

P. E=60×10×20

P. E=12000joules

We know

P. E=w

Hence

P =w/t

=12000/120

=100 joules per second
