Consider an object rolling off of your lab bench. Discuss how you might be able to make measure- ments to determine its initial velocity when leaving the bench. (a) What evidence have you previously collected that makes you think your method for answering this question is feasible?

measure the position every so often with a stopwatch

Explanation:

A possible method of measurement is to place a measuring tape along the path and measure the position every so often with a stopwatch, with this we can make a graph of position against time and by extrapolation find the initial velocity.

This is a method used in measurements of uniform movements of bodies

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6
