Answer:
14.91 Joules
Explanation:
First you just plug stuff into the potential energy due to gravity equation [Potential Energy=acceleration due to gravity * Mass * Height].
PEg= (9.81m/s2)*(2kg)*(0.76 m) <<<<<<<<
(Just plug in all the values)
We get PEg= 14.91 Joules
Physics is pretty much just converting one unit to another, Joules are also known as (kg m2/s2)
