A 48.5-g Super Ball traveling at 29.0 m/s bounces off a brick wall and rebounds at 17.5 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.55 ms, what is the magnitude of the average acceleration of the ball during this time interval

the assestment will probley apele with cause and effect

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.
