Assess what information you are given. 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. Sodisplacement in between 2s and 5s is s 3t25 2 6t5 2 325 4 65 2 45m.
Using Calculus to Find Acceleration Acceleration is measured as the change in velocity over change in time DVDt where D is shorthand for change in.
The average speed is the total distance travelled divided by the time. Instantaneous speed is the speed at which an object is traveling at any particular instant. Average speed s Total distance Elapsed time. This video explains the distinction between average speed and instantaneous speed.
