Question

How high up is a 3 kg object that has 300 joules of energy

Answer 1

You use the Work Formula
W=F*d
or W=mgh
So W = 300 J
m= 3kg
g = 9.8
an d you have to find h
so 300 = 3*9.8*h
h=10.2m

Answer 2

Answer:

Height, h = 10.20 meters

Explanation:

It is given that,

Mass of the object, m = 3 kg

Energy of object, E = 300 J

Let it will moved to a height of h. The energy possessed by it is called gravitational potential energy. It is given by :

$E=mgh$

$h=\dfrac{E}{mg}$

$h=\dfrac{300\ J}{3\ kg\times 9.8\ m/s^2}$

h = 10.20 meters

So, the object will move to height of 10.20 meters. Hence, this is the required solution.
