The drawing shows a person looking at a building on top of which an antenna is mounted. the horizontal distance between the person’s eyes and the building is 95.2 m. in part a the person is looking at the base of the antenna, and his line of sight makes an angle of 30.4o with the horizontal. in part b the person is looking at the top of the antenna, and his line of sight makes an angle of 33.8o with the horizontal. how tall is the antenna?

i don't know that i agree with that but what's the question ?

chemical energy --> gravitational potential energy --> kinetic energy --> elastic potential energy --> gravitational potential energy

explanation:

when emma starts the hike, the chemical energy stored in her body is used to climb up the mountain, and so she gains gravitational potential energy (because at the end, she will be at a higher height h above the ground). then she goes bungee jumping: as she falls, this gravitational potential energy is converted into kinetic energy (because her speed increases as she falls down), until the point when the rope stretches, and she stops moving. at that moment, all the kinetic energy is converted into elastic potential energy due to the stretching of the rope. then, this energy is released because the rope returns to its natural length, and emma gains a small increase in altitude , so she gains some gravitational potential energy.
