Answer:
[tex]15\:\mathrm{J}[/tex]
Explanation:
The potential energy of an object is given by [tex]PE=mgh[/tex].
Recall that the weight of an object is equal to the force of gravity on the object. From this, we can set up the following equation and solve for the mass of the object:
[tex]F=mg,\\5=mg,\\m=\frac{5}{9.81}\approx 0.51\:\mathrm{kg}[/tex]
Now we can plug in values to [tex]PE=mgh[/tex] and solve:
[tex]PE=0.51\cdot9.81\cdot3=\fbox{$15\:\mathrm{J}$}[/tex].
Answer:
The potential energy of the body is 15J.
Explanation:
What is potential energy?
The energy possessed to a body due to position is called Potential energy.
U=mgh
- Given data:
- weight (mg)=5N
- height (h)=3m
- Potential energy (U)=?
- by using formula
U=mgh
U=5×3=15J
Hence, the potential energy of the body is 15J.
