You need speed to calculate this. Distance is speed / time

You need the mass (m) and volume (v) of the object. The density (d) is then given by:d = m / v

Need average speed to calculate.

You can calculate a speed by dividing a distance by the time it takes to cover that distance. If you want the instantaneous speed (for situations of variable speed), you need to calculate the distance and time for a fairly short time interval (ideally, the limit, when the time approaches zero).

Speed and time. As acceleration is the change in speed over time.However, if you do not have a direct reading of speed, you will need to claculate that also, from distance over time.So all the units are:-Distance = MetresTime. = SecondsSpeed = m/sAcceleration = m/s/s or m/s2

There are not enough measurements to calculate square yards. It would need to be 7500 by (another measurement) to calculate.

Speed and Velocity are two different things . Velocity- "the rate at which an object changes its position." Speed- "How fast an object is moving". To calculate speed and velocity, you first need to calculate distance and time. Velocity is considered to be a more logical term
