Prove that v=u+at

$\bold{ \underline{ \underline{ \green{SOLUTION}{} }{} }{} }{}$

We know acceleration (a) = rate of change in Velocity.

★Acceleration = Rate of change in Velocity/Time

★Since Rate of change in acceleration means that the difference in Initial Velocity(u) and Final Velocity (v)

★Since acceleration = V-u /t

★ acceleration = V-U /t or a *t = v - u

★Therefore,

» V = u+at

geostationary satellite

it is artificial satellite , which appears stationary to an observer in the Earth's surface.

conditions for satellites to appear geostationary

time period will be 24 hours

it's orbit should be in equatorial plane of the earth
