4.10 m/s
Explanation:
V=x/t, therefore v=50m/12.2s=4.10m/s
Answer:
The total energy in a closed system (a system that isolated from its surroundings) is always constant.
Explanation:
The law of conservation energy states that:
The total energy in a closed system (a system that isolated from its surroundings) is always constant.
What this law means is that energy can never be created or destroyed but can only be converted from one form to another form or example the conversion of energy from potential energy to kinetic energy which is seen by a falling object from a height.
Answer: Work is done when a spring is extended or compressed . Elastic potential energy is stored in the spring. The elastic potential energy stored can be calculated using the equation: elastic potential energy = 0.5 × spring constant × (extension) 2.
