Answer:
m = 5.0968 kg
Step-by-step explanation:
The page you have posted contains bunch of the problems and you haven't specified the question number to be answered. So I'm solving 1 question on the page( number 13)
13) Potential Energy of object P.E. = 600 J
Gravitational acceleration g= 9.81 m/s²
Height from the ground h = 12 m
Let m is the mass of the object.
We know P.E. = mgh
600 = m×9.81×12
m = 600/117.72
m = 5.0968 kg
So w = mg
= 50N
