As we know that collision is elastic so we will have
also we can use momentum conservation
now from above two equations we will have
also we have
so both balls will separate after collision and move in opposite direction as the final velocities are opposite in sign
So correct answer will be
<em>D. The balls separate and move in opposite directions.</em>
Answer:How is potential energy converted to thermal energy in a system?
Explanation:
A substance undergoing a physical change will still weigh the same even after the change. This is in accordance to the law of conservation of mass which states that mass is neither created nor destroyed. so an 8 g substance remains of the same weight even after undergoing a physical change.
Typically your target heart rate is used for that. you can track and guide your exercise intensity by calculating your target heart rate range
