Define average velocity and instantaneous velocity when are they same

Look to the explanation

Explanation:

Average velocity: is the average rate of change of displacement with

respect to time

Average velocity is a measure for distance traveled in a given time

We can calculate the average velocity by the rule

where s is the displacement and t is the time

Instantaneous velocity: is the velocity of an object in motion at a

specific point (x , t)

instantaneous velocity is the limit of velocity as the change in time

approaches zero

We can calculate the instantaneous velocity by the rule

Average velocity is equal to the instantaneous velocity when

acceleration is zero

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
