Which formula is used to find average velocity?
|
Vavg = (rfinal-rinitial)/(tfinal-tinitial)
|
|
Vavg = (rinitial-rfinal )/(tinitial-tfinal )
|
|
Vavg = (afinal-ainitial)/(tfinal-tinitial)
|
|
Vavg = (ainitial-afinal)/(tinitial-tfinal)
|
Explanation:
Detailed explanation-1: -EXPLANATION: If final Velocity v and Initial velocity u are known, then the formula for the average velocity is given by: Vav = (u + v)/2.
Detailed explanation-2: -The equation is s = ut + 1/2at^2, where s-distance, u-inititial velocity, and a-acceleration.
Detailed explanation-3: -One simple way to calculate the distance covered is to use the formula for average velocity: vavg = distance or vavg = ∆x time t Page 2 2 | Page Physics Lecture #4 Find the distance covered by a car moving at an average velocity of 12 m/s for 4.0 seconds.
Detailed explanation-4: -¯v = average velocity. v = final velocity. u = initial velocity.
