1. When a golf ball is hit, it travels at 41 meters per second. The mass of a golf ball is 0.045 kg. What is the kinetic energy of the golf ball?
2. the newly developed F-22 Raptor jet fighter weighs approximately 100,000kg and can travel up to 600 meters per second what is the kinetic energy of the F-22 jet fighter at this speed
3. if the jet fighter in #2 is traveling at a height of 10,000 meters, what would the potential energy be

Answers

Answer 1
F-22 is the correct answer
Answer 2

(1) The kinetic energy of the golf ball is 37.82 Joules,

(2) The kinetic energy of the F-22 jet fighter is 1.8 × 10¹⁰ Joules.

(3) The potential energy of the  F-22 jet fighter is 9.8 × 10⁹ Joules .

What is kinetic energy?

Kinetic energy is a type of power that a moving object or particle possesses. When an object undergoes work, which involves the transfer of energy, by exerting a net force, the object accelerates and consequently obtains kinetic energy.

Given:

The velocity of the ball, v = 41 m / s,

The mass of the golf ball, m = 0.045 kg,

(1)  Calculate the kinetic energy as shown below,

KE = 1 / 2 × 0.045 × 41²

KE  = 37.82 Joules

(2)  Calculate the kinetic energy of the F-22 jet fighter as shown below,

KE = 1 / 2 × 600² × 100000

KE = 1.8 × 10¹⁰ Joules

(3)  Calculate the potential energy of the jet as shown below,

PE = 100000 × 9.8 × 10000

PE = 9.8 × 10⁹ Joules

ОВ.
The track pushes in the same direction as Clinton's shoe with the same force.
OC. The track pushes against gravity with the same force.

The track pushes in a different direction with a different force.

Answers

Answer:A:The track pushes back on Clinton's shoe with the same force.

Explanation:According to Newton's third law of motion, for every action force there is an equal and opposite reaction force. In this case, the action force is Clinton's shoe pushing on the track. As this happens, there is an equal and opposite reaction force in which the track pushes back on Clinton's shoe with the same force.

A 3500 N is force is applied to a spring that has a spring of constant of k= 14000 N/m. How far from equilibrium will the spring be displaced?

Answers

Answer:

the spring be displaced by 25.0 cm

Explanation:

The computation is shown below:

As we know that

F= -K × x

So,

[tex]x = \frac{-F}{K}[/tex]

Now  

[tex]x = \frac{-3500}{14000} \\\\[/tex]

= -0.250m

= 25.0 cm

Hence, the spring be displaced by 25.0 cm

Do you think we might have problems with not enough water to supply our needs (water scarcity) in the
ture? Why or why not? If you answered yes, what might the causes be?

Answers

Answer:

Water scarcity (water stress or water crisis) is the lack of fresh water resources to meet the standard water demand. Humanity is facing a water crisis, due to unequal distribution (exacerbated by climate change) resulting in some very wet and some very dry geographic locations, plus a sharp rise in global freshwater demand in recent decades driven by industry. Water scarcity can also be caused by droughts, lack of rainfall, or pollution. This was listed in 2019 by the World Economic Forum as one of the largest global risks in terms of potential impact over the next decade.[1] It is manifested by partial or no satisfaction of expressed demand, economic competition for water quantity or quality, disputes between users, irreversible depletion of groundwater, and negative impacts on the environment.[2] Two-thirds of the global population (4 billion people) live under conditions of severe water scarcity at least 1 month of the year.[3][4][5][6] Half a billion people in the world face severe water scarcity all year round.[3] Half of the world's largest cities experience water scarcity.[5]
