Answer:
Uniform velocity involves a straight-line motion over equal distance and in equal time intervals. Non-uniform motions involve unequal distances in equal interval of time.
Explanation:
A body moving with uniform velocity occurs when it travels in a straight line path, and covers equal distances in equal time intervals.
Example a graph of a bike covering equal distance in equal time intervals.
A body moving with a non-uniform velocity occurs when it travels to cover unequal distance in equal intervals of time. Example a bike travelling in a crowded road.
Answer:
The transmission of energy is one thing that is carried out by all kinds of waves. They transmit energy from one point, known as the source, to another point.
For instance, in electromagnetic waves, energy is transmitted as a result of vibrations between the magnetic field and electric field. In mechanical waves, energy is transmitted when the particles in the medium heat up and vibrate. Energy travels through particles in a medium.
Answer:
t = 025 s
Explanation:
We know
weight, W = 4 pounds
spring constant, k = 2 lb/ft
Positive damping, β = 1
Therefore mass, m = W / g
m = 4 / 32
= 1 / 8 slug
From Newtons 2nd law
where x(t) is the displacement from the mean or equilibrium position. The equation can be written as
Substituting the values, the DE becomes
Now the equation is
and on solving the roots are
= 
= -4
Therefore the general solution is 
Now for initial condition x(0) = -1 ft
x'(0)= 8 ft/s
Now we can find the equation of motion becomes,
Therefore, the mass passes through the equilibrium when
x(t) = 0
= 0
-1+4t = 0
t = 
= 0.25 s
