QUESTION 11

• How long will it take a boat, moving at 5.6 m/s, to travel 100 meters?

QUESTION 12

• Pick the correct statement regarding velocity and speed.

QUESTION 13

QUESTION 14

• A car is driving at a certain speed. Unfortunately, there is an oil leak and the car drops a plop of oil on the ground every second the car is in motion. The oil drop pattern looks like ...

• Start*     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *     *

• You collect time (X - indepentent variable) and displacement of car (Y - independent variable) data by measuring how far the car has traveled from the starting point as each second goes by. Graph the data below using EXCEL and SELECT the likely mathematical relationship between displacement and time.

• You collect time (X - indepentent variable) and displacement of car (Y - independent variable) data by measuring how far the car has traveled from the starting point as each second goes by. Graph the data below using EXCEL and, based on your data and graph, determine the SLOPE (Rate of Change), of the displacement with respect to time. What does the slope of the displacement vs time graph represent?
