Answer:
5.292 Joules
Explanation:
Hello
applying the law of the conservation of energy, and assuming that no energy is lost due to friction with the air, we can affirm that the energy that has just before the impact is the same energy that it has just before being released, that energy is due to height, mass and gravity and is defined by:
[tex]E_{g}=m*g*h\\\\now\\E_{p} =E_{g}=m*g*h\\E_{p}=m*g*h\\[/tex]
Let
[tex]m=0.3kg\\g=9.8\frac{m}{s^{2} }\\ h=1.8\ m[/tex]
pute the values into the equation
[tex]E_{p}=m*g*h\\E_{p}=0.3 kg*9.8\frac{m}{s^{2} }*1.8\m\\E_{p}=5.292\ Joules\\[/tex]
Have a nice day.
