Answer:
The change of energy is 60J
Explanation:
We have a closed system, which receives 80 J of energy. It means this energy is entering the system. And also we have 20 J that is dissipating in the shape of heat.
Therefore the amount remaining in the system will be 80 - 20 = 60 J
If .45y = 65
Then solving for y would give you: <span>y = 144</span>
Answer:
*1) 100 Joule energy
*2) 101.2 m/s
Explanation:
*1) 1J = 1w
100J = 100w
*2) A 70-kg person will have to run at a speed of 101.2 m/s to have that amount of kinetic energy.
