ANSWER: Kinetic Energy is the energy of mass in motion. In a rescue mission, kinetic energy is the most used energy to carry out the rescue operation successfully. The energy of the people involved in the rescue mission is a form of kinetic energy. The machineries involved in the rescue mission like helicopters, submarines, lifeboats are all examples of kinetic energy. To sum up, anything that moves and has a role in rescuing the victims can be termed as the kinetic energy involved in rescue team missions.
Answer:
Explanation:
1.{1,3}2. adn as if bruh ma dude
False it only melts when its thermal energy increases. plus an ice cube has no mechanical energy.
Answer:
The change of the momentum of the ball is 
Explanation:
We should find 
(1)with 
the initial momentum and 
the final momentum. Linear momentum is defined as 
, using that on (1):
(2)
It's important to note that momentum and velocity are vectors and direction matters, so if +x direction is the direction towards the wall and the -x direction away the wall 
and 
so (2) becomes:
