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
​

Respuesta :

Answer:

1. 37.8J

2. 18 Billion Joules, 18 Gigajoules

3. 9.81 Billion Joules, 9.81 Gigajoules

Explanation:

Use the formulas provided,

KE=(1/2)mv^2 and PE=mgh, noting that g=9.81
F-22 is the correct answer
