, b) 
, 
, 
Explanation:
a) The system mass-spring is well described by the following equation of equilibrium:
After some handling in physical and mathematical definition, the following non-homogeneous second-order linear differential equation:
The solution of this equation is:
The velocity function is:
Initial conditions are:
Equations at 
are:
The spring constant is:
After some algebraic handling, amplitude and phase angle are found:
The position can be described by this function:
b) The period of the motion is:
The amplitude is:
The phase of the motion is:
Answer:
1. Static electricity has two charges magnetism has two poles.
2. Same charges and same poles repel and opposite charges and poles attract.
3. Static electricity is produced by charges(at rest) Magnetism is produced by charges(moving with uniform speed)
Answer:
1000N,4.48m/s
Explanation:
Height(h) = 1m
P. E = 1000J
P. E = mass x acceleration due to gravity x height
Acceleration due to gravity = 10m/s
P. E = mgh
Where weight = mg
P. E = weight x height
Weight = P. E / height
Weight = 1000 / 1
Weight. 1000N
b) as he leaves the ground P. E = K. E
P. E = 1/2 mv2
P. E = 1000 , mass = weight / 10
Mass =1000/10 = 100kg
P. E = 1/2 mv2
1000 = 1/2 x 100 x v2
Multiply both sides by 2
1000 x 2 = 100 x v2
V2 = 2000/ 100
V2 =20
Square root both sides
V = square root of 20
V = 4.48m/s
