2. instantaneous speed is the rate of motion of an object at a particular moment in time. what change(s) to the experimental procedure would be necessary if you wanted to gather data on instantaneous speed?

To gather data on instantaneous speed via experiment, we can use limits i.e. using limits in the formula for example 1 second and 2 second interval with particular difference of distance traveled by object during this interval. for example if distance traveled after 2 second is 60m and after one second is 35m, then the speed will be the ratio of differences of distances and time intervals.
