Answer:
Simple harmonic motion is the movement of a body or an object to and from an equilibrium position. In a simple harmonic motion, the maximum displacement (also called the amplitude) on one side of the equilibrium position is equal to the maximum displacement.
The force acting on an object must satisfy Hooke's law for the object to undergo simple harmonic motion. The law states that the force must be directed always towards the equilibrium position and also directly proportional to the distance from this position.
The answer is 1/4
this is actually a very simple question because if you divide 3,600 by 4 that equals 900 so if you want them to be the same waight you need 3,600 to be multiplied by 1/4.
The area of the graph of acceleration time is at
at = v - u
-10 = v - 25
v = 15 m/s
Answer:
final velocity will be equal to 8.28 m/sec
Explanation:
Let the mass is m
Height fro which it is fallen h = 3.5 m
Acceleration due to gravity 
We have to find the final velocity of the mass
As the mass is dropped from rest so initial velocity is 0 m/sec
Using energy conservation 
So 
So final velocity will be equal to 8.28 m/sec
