Answer:
It have 1.359 joule kinetic energy.
Explanation:
- Kinetic energy is defined as the energy of any object due to its state of motion.
- Mathematically kinetic energy can be calculated as:
K.E = 
...........................equation 1
where,
m= mass of object
v= velocity of that moving object
mass= 2500 lbs =
kg.
velocity= 80mph=
=
.
- Substituting the values in equation 1, we get;
K.E=
*
* 
K.E= 
Answer:
Discovered different planets.
Explanation:
I strongly disagree. There are many other planets in our solar system that have gravity on them. The statement is false. I hope this helps.
