Below are the answers:
a. <span>DE=421.875-76.8=-345.075 joules (negitive sign means that the energy is transfering out of your system ie slowing down)
b. </span><span>work=DE (work done is change in energy)=-345.075 joules
c. </span><span>W=f*d </span>
<span>d=w/f </span>
<span>d=345.075/10 </span>
<span>d=34.5075 meters</span>
The correct answer is C. Even though the potential energy can be stored, but it is connected with coordinate system.

Explanation:
The following processes/events take place in the cooling of a fluid.
- A reduction in the kinetic energy of the molecules of the fluid
- The molecular speed reduces ( i.e.there will be a reduction in the speed at which the molecules move)
- The cohesive force between the molecules will increase ( i.e the molecules will no longer be drifted apart, they will now move closer to each other
- The temperature of the fluid reduces as it cools down
- There will be an increase in density
Answer: The surface of the pad pushes the rocket up while gravity tries to pull it down. As the engines are ignited, the thrust from the rocket unbalances the forces, and the rocket travels upward. Later, when the rocket runs out of fuel, it slows down, stops at the highest point of its flight, then falls back to Earth.
