Answer:
T = 0.71 seconds
Explanation:
Given data:
mass m = 1Kg, spring constant K = 78 N/m, time period of oscillation T = 0.71 seconds.
We have to calculate time period when this same spring-mass system oscillates vertically.
As we know
This relation of time period is true under every orientation of the spring-mass system, whether horizontal, vertical, angled or inclined. Therefore, time period of the same spring-mass system oscillating vertically too remains the same.
Therefore, T = 0.71 seconds
4 because its not yet moving. It has kinetic energy, it just hasn’t been used yet.
Gravitational energy is the potential energy associated with gravitational force. If an object falls from one point to another inside a gravitational field, the force of gravity will do positive work on the object and the gravitational potential.

-- Energy from the sun was absorbed by grass, grain, and hops, making it possible for them to grow.
-- The grass was eaten by livestock, and turned into stored beef energy.
-- The grain was harvested, pounded into flour, baked, and turned into stored bread energy.
-- The hops were harvested, soaked, and turned into stored beer energy.
-- Johannes Brahms ate beef, which his body turned into brain and muscle energy. Ludwig van Beethoven drank beer, which his body turned into energy and inspiration. John Phillip Sousa ate bread, which his body turned into leg energy to march with.
-- All of these individuals, and a lot of others, composed music which nobody had ever heard before, using the solar energy they absorbed from the stuff that they ate and drank.
The box moved 0.73 m
<u>Explanation:</u>
Given data,
Magnitude 8.1 N Work on the box 5.9 J Clerk move a 4.4 Kg
Distance= work done on the box / Horizontal force on the magnitude
= 5.9/8.1
=0.728
Distance =0.73 m
The box moved 0.73 m
