Three Types of Solutions of a System of Linear Equations. There are three possible outcomes for a system of linear equations: one unique solution, infinitely many solutions, and no solution. This video shows an example of each type of outcome.
Answer
given,
mass of the block = 200 g = 0.2 Kg
Velocity at A = 0 m/s
Velocity at B = 8 m/s
slide to the horizontal distance = 10 m
height of the block be = 4 m
potential energy of the block
P = m g h
P = 0.2 x 9.8 x 4
P =7.84 J
kinetic energy
Work = P - KE
work = 7.84 - 6.14
work = 1.7 J
b) v² = u² + 2 a s
0 = 8² - 2 x a x 10
a = 3.2 m/s²
ma - μ mg = 0
Answer:
-1.46 m/s^2
Explanation:
Write down what is given first:
v0 = 12 m/s
vf = 0 m/s
d = 45 m
We are trying to find acceleration, so we will use the equation vf^2 = v0^2 + 2ad
Plug in the values we have:
0^2 = 12^2 + (2 x 45 x a)
a = - 1.46 m/s^2
Note that this acceleration is negative because the body is slowing down, so the acceleration with be negative, because the change in velocity is negative.
The motion of particles during the transmission of wave energy
is periodic. A periodic wave is a continuous oscillating motion that connects
with simple harmonic motion. It is usual that periodic wave particles also
experiences simple harmonic motion. Additionally, the particles on the surface
of the water travel in circular motions forming a wave across the surface.
Answer:
Average net force, F = 15157.15 N
Explanation:
It is given that,
The mass of the car and riders is,
Initial speed of the car, u = 0
Final speed of the car, v = 43.4 m/s
Time, t = 8.59 seconds
We need to find the average net force exerted on the car and riders by the magnets. It can be calculated using second law of motion as :
F = m a
F = 15157.15 N
So, the average net force exerted on the car and riders by the magnets. Hence, this is the required solution.
