Given a constant acceleration and assuming linear motion, derive equations for velocity and position of a body with respect to t
uysha [10]

Answer:

v = at + u

x = ut+\frac{1}{2}at^{2}+x_{0}

Explanation:

acceleration, a = constant

As we know that acceleration is the rate of change of velocity

a=\frac{dv}{dt}

dv=adt

integrate on both sides

\int dv=\int adt

v = at + u

Where, u is the integrating constant and here it is equal to the initial velocity

Now we know that the rate of change of displacement is called velocity

v = \frac{dx}{dt}

dx=vdt=(u+at) dt

Integrate on both sides

\int dx=\int (u+at) dt

x = ut+\frac{1}{2}at^{2}+x_{0}

where, xo is the integrating constant which is initial position of the particle.

Which term describes the object that a satellite revolves around?
m_a_m_a [10]

The object that a satellite revolves around is the <em>central body</em> of the system. <em>(C)</em>

For example:

-- The central body of the solar system is the Sun.

-- The central body for TV satellites, GPS satellites, weather satellites, and the International Space Station is the Earth.

-- The central body for Phobos and Deimos is Mars.

This should be a pretty easy question to answer by elimination, when you notice that "Orbit", "Period", and "Rotation" are not "Bodies".
