Answer: The total mechanical energy stored in an apple is 1.47 Joules
Explanation:
Mass of the apple = 0.100 kg
Height at which apple is hanging = 1.50 m
Force on the apple = [tex]Mass \times g[/tex]
Velocity of the apple = 0 m/s
g = acceleration due gravity
Mechanical energy = Potential energy + Kinetic energy
= [tex]mass\times g\times height[/tex] + [tex]\frac{1}{2}mass\times (velocity)^2[/tex]
[tex]=0.100 kg\times 9.8 m/s^2\times 1.50 m+\frac{1}{2}\times 0.100 kg\times (0 m/s)^2=1.47 Joules[/tex]
The total mechanical energy stored in an apple is 1.47 Joules
