Question

A 10kg weight is suspended from the ceiling by a spring. The weight spring system is at equilibrium with the bottom of the weight about 1m above the floor. The spring is then stretched until the weight is just above the eggs. When the spring is released, the weight is pulled up by the contracting spring and then falls back down under the influence of gravity. On the way down it,
A)Reverses its direction of travel well above the eggs
B)Reverses its direction of travel precisely as it reaches the eggs
C)Makes a mess as it crashes into the eggs

Explain reasoning

Explanation / Answer

Its simply conservation of energy principle. When you pull the spring potential energy is developed in the spring.when you release the spring there is no other energy in the spring except the potentia energy supplied by you.Thus this potential energy is converted to kinetic energy at mean level and converted back to potential energy in compressed level .So there wont be any extra extension in the spring. B)Reverses its direction of travel precisely as it reaches the eggs **is the answer visit the link provided below for more info about the subject
