Answer:
A) When the baseball is rising
Explanation:
When an object like the baseball is thrown into the air, the kinetic energy is gradually converted into potential energy. When the baseball rises to its maximum height, the kinetic energy becomes zero and the kinetic energy is fully converted into potential energy.
I, i’m pretty sure sorry if it’s wrong
Treatment water from the plant would affects the communities present in the downstream of the river.
Answer: Option (a)
<u>Explanation:</u>
Wastewater treatment plant is a process used to treat the water that flows from the rivers, streams, and lakes.This plant removes the dust, sand, sediments present in the river water.
When this treated water is released into the downriver stream, it affects the health of aquatic organisms present in that stream.Use of chemicals in treating the wastewater may cause genetic problems to the communities present in that region.
It also causes air pollution and more energy is needed for the treatment process and thus affects the ecosystem.

Let's solve ~
Given terms :
The formula to find kinetic Energy is ~

Now, apply the formula according to given situation




Therefore, the kinetic Energy of the car is 56 joules
