Question

an an object of mass 40 kg is raised to out of 5 m above the ground what is a potential energy is the object allowed to fall find the kinetic energy when its half a way down​

Answer 1

MASS =40KG
HEIGHT=5M
LET GRAVITY BE 10m/s
P. E=mgh
=40*5*10=2000 joule.
K. E=1/2mv^2

Answer 2

_/\_Hello mate__here is your answer--

_______________________

Given:-

m = 40 kg

g = 9.8 m/s^2

h = 5 m

We know that,

potential energy = mgh

= 40 × 9.8 × 5 J

= 1960 J

_______________________

♦♦The total mechanical energy (Kinetic and potential energy) of an object remains constant. (law of conservation of energy)

Therefore, when the object is half-way down, its potential energy become half the original energy and remaining half converted into kinetic energy.

Hence, the kinetic energy = ½ (1960) J = 980 J

I hope, this will help you.☺

Thank you______❤
