Question
A 0.2 kg apple is hanging from a tree 6 meters above the ground How much potential energy does the apple have? If the apple falls (the apple a a projectile while falling). haw much kinetic energy will the apple have right as it hits the ground? Ignore air resistance the apple has _ J of potential energy when it is hanging the tree, the apple will have _ J of kinetic energy as it this the ground A 0.2 kg apple Is hanging from a tree 6 meters above the ground. Suddenly. the branch breaks and the apple falls. The apple has _ J of kinetic energy right after the branch breaks the apple has _ J of kinetic energy after it has fallen halfway down the apple has of _ J potential energy after it has fallen halfway down A certain spring has a spring constant of 111 N/m How much elastic potential energy is in the spring If It is stretched out 0.3 maters? It takes 50 N of force to stretch a certain spring 0.5 meters. What is the spring constant (k) of the spring? _ N/m How much force would it take to stretch that same spring 0.65 meters? _ N How much elastic potential energy -s stored in this spring if it is stretched out 0.85 meters? _ JExplanation / Answer
2)
Just after the branch is broken it has no velocity
So kinetic energy is zero
When it is half fallen half of the potential energy converts to kinetic enwrgy
So kinetic energy = 0.2 gx3 = 5.88J
Potential energy after falling half distance
Potential energy = 5.88J
