Question

1. What is the mechanical energy (sum of PE +KE) throughout her trip? 2. Where is potential energy the highest? 3. Where is kinetic energy the highest? 4. Relationship statement: Height above ground to potential energy. As 5. Relationship statement: Speed (velocity) to kinetic energy. As

Answer 1

1)50000J

2) At the start of the trip

3) At the end of the trip

4) The higher the height above the ground, the higher the potential energy

5) As speed increases, Kinetic Energy increase
