Answer:
The gravitational potential energy of the can dropped from a shelf that is 1.5 m high, is 10.29 J. Rounding the answer to the nearest tenth of a joule, we have that the potential energy is 10.3 J.
Explanation:
The potential gravitational energy can be written as
[tex]V=mgh[/tex]
where m is the mass of the object, g is the gravitational acceleration, and h is the altitude of the object.
One thing we must understand is that V is a relative quantity, so we need to establish an altitude where V=0, in this case, the zero potential could be at the floor, so the altitude where the can is beeing dropped is h=1.5m.
Doing this, we have that
[tex]V=(0.7kg)*(9.8\frac{m}{s^2})*(1.5m)=10.29J[/tex]
and when rounded, we have the final answer:
[tex]V=10.3J[/tex]
