<span>The answer is, 7.44 kg*m/s</span>
Answer:
The forms of energy involved are
1. Kinetic energy
2. Potential energy
Explanation:
The system consists of a ball initially at rest. The ball is pulled down from its equilibrium position (this builds up its potential energy) and then released. The released ball oscillates due to a continuous transition between kinetic and potential energy.
Answer:
The object has 1250 Joules of Kinetic Energy.
Explanation:
Kinetic Energy = 
mass*velocity²
KE = mv²
KE = (100kg)(5m/s)²
KE = (100kg)(25m/s²)
KE = 1250
KE = 1250J
Answer:
Answer D: It describes the relationship between motion and force.
Explanation:
The answer is D because a law is something that describes something in nature, but does not try to explain how or why is occurs (that is a theory). Options B and C sound more like theories, while option A sounds like a definition. Option D is correct because a law describes without explaining.
