Question

I honeslty just need the answer .

Answer 1

38Watts

Step-by-step explanation:

Given parameters:

Mass = 75kg

height = 8.5m

time = 165s

Unknown:

Power = ?

Solution:

Power is the rate at which work is done.

Power =
`(work done)/(time)`

Work done = mgh

m is the mass

g is the acceleration due to gravity = 9.8m/s²

h is the height

Now insert the parameters and solve;

P =
`(75 x 9.8 x 8.5)/(165)` = 38Watts
