Question

A 2 kg box of taffy candy has 40j of potential energy relative to the ground. Its height above the ground is​

Answer 1

2.04m

Step-by-step explanation:

PE=mgh

h= PE/mg

h= 40/2(9.82)

h=40/19.64

h=2.04

Answer 2

`20m`

Step-by-step explanation:

Formula to find the potential energy is,

Potential Energy = mgh

Here,

m = mass

g = gravitational field

h = height

According to the question, we have to find the height.

Usually, we get g is
`10ms^(-2)`

Let us solve for the answer now.

`P.E. =mgh\\40J =2kg*10ms^(-2) *h\\40 = 20h\\(40)/(20)= (20h)/(20) \\20m=h`

Hope this helps you.
