drag each label to the correct location on the image. each label can be used more than once, but not all labels will be used. emma is an adventurer. she hikes up a mountain to go bungee jumping. complete the energy chain diagram representing the energy transformations that emma and the rope encounter. elastic potential energy chemical potential energy electric potential energy motion energy gravitational potential energy emma standing on top of mountain emma jumping down from mountain top tension in rope at emmas lowest position emma bouncing back reset next
Answer
Answer:
Emma standing on top of mountain: gravitational potential energy Emma jumping down from mountain top: motion energy tension in rope at Emma's lowest position: elastic potential energy Emma bouncing back: motion energy
Explanation:
Step1: Initial position
When Emma is standing on top of the mountain, she has height above the ground level. Gravitational potential energy is given by $U = mgh$ (where $m$ is mass, $g$ is acceleration due to gravity and $h$ is height), so she has gravitational potential energy.
Step2: During jump
As she jumps down from the mountain - top, her height decreases and her speed increases. The gravitational potential energy is converted into motion energy (kinetic energy $K=\frac{1}{2}mv^{2}$, where $v$ is velocity).
Step3: At lowest position
When she reaches the lowest position, the bungee - rope is stretched to its maximum. The motion energy is converted into elastic potential energy stored in the stretched rope, given by $U_{s}=\frac{1}{2}kx^{2}$ (where $k$ is the spring constant of the rope and $x$ is the extension).
Step4: Bouncing back
As the rope recoils and she bounces back, the elastic potential energy stored in the rope is converted back into motion energy as her speed increases again.
