Plz asap will mark brainliest for the correct answer

a book weighing 30kg is lifted 10m in 5.5 sec. how much power did it take? p=w/t

It takes 534.54 watts

Step-by-step explanation:

Given :

Mass of the book = 30kg

Distance  = 10m

Time  =  5.5 sec

To Find:

How much power did it take = ?

Solution:

Step 1:  calculate the work done

Work done  =

where

m =  mass

a = acceleration due to gravity

d =  distance

Substituting the values,

Work done  =

=> 2940 Nm

Step 2:  calculate the Power

We know that

Substituting the values,

Power = 534.54 watts

if x = 1, then the answer is 3.5

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
