1. The problem statement, all variables and given/known data 1.What is the highest potential energy? 2.What is the biggest change in kinetic energy? 3.If the track is only designed to uses electricity to pull the cars up the first incline, does the rollercoaster experience conservation of mechanical energy? Explain your answer. 2. Relevant equations 3. The attempt at a solution 1. highest potential energy would be at the start, point A where there is no movement 2. Biggest change in kinetic energy is the steepest hill, point d, mgh=1/2mv^2 3. This one i have no clue how to explain, im kind of confused. Please help me with #3 and explain it to me please!
