A 2.2 kg book has been dropped from a shelf. Its speed is 4.7 m/s when it is 1.3 m above the ground. What is its mechanical energy at this point?
An 18 kg child is on a swing traveling at 3.8 m/s at the lowest point. What will be the height of the swing at the highest point?
A 500 kg roller coaster starts from rest at the top of a 95 m hill. What is its speed at the bottom of the hill? (number only rounded to nearest tenth ex: 76.3)
Yareli has 2000 J of potential energy when she is standing still on a diving board. What is her mechanical energy at this point?
The potential energy at the top of a cliff equals the kinetic energy at the ground level (assume no air resistance occurs).
