$\huge \underline \bold \green{QUESTION}:$

a 17 of box during on a shelf had a potential energy of 350j . how height is the shelf. round of the answer to a whole number

__________________________

$\huge \underline \bold \red{SOLUTION}:$

the potential energy of a body is mgh here

m = 17

PE = 350j

g= 9.8m/s²

h=?

PE = mgh

350= 17*9.8*h

$h = \frac{350}{17 \times 9.8} \\ h = 2.1$

__________________________

$\underline\bold \red{final \: answer}$

$h = 2.1 \\ when \: we \: round \: of \: it \: to \: a \: whole \: number \: \\ we \: get \: \\ \huge{h \: = 2}$

__________________________

$\underline\bold \red{formulas \: used}$
