Ds refers to the change in position. Velocity v is a vector quantity that measures displacement or change in position Ds over the change in time Dt represented by the equation v DsDt. For an object that is uniformly accelerated however there is another formula one could use.
The average velocity is the sum of the final and iitial velocity divided by 2.
For our example the bikes initial velocity v i is 5 ms. For an object that is uniformly accelerated however there is another formula one could use. The average velocity of the train during this time is. Use this formula to find average velocity.
