A position versus time graph is shown: (2 points) A Position versus Time graph is shown with y-axis labeled position in centimeters up to 15 and x-axis labeled time in seconds up to 10. A straight line connects the points 0, 0 and 3, 3. A horizontal line connects points 3, 3 and 6, 3. A straight line connects 6, 3 and 10, 11. Which statement accurately describes the motion of the object in the graph above?

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

a. carbon monoxide from car exhaust

b.particulate matter, such as soot

c.water vapor from a factory smokestack
