Question 1 The y-axis, representing velocity, is scaled so that each square (vertical division) represents 6 m/sec. The x-axis is scaled so that each square represents 1 second.

What was the cart's instantaneous speed at 14.7 seconds?

-12.00 m/sec12.00 m/sec-0.74 m/sec0.74 m/sec cannot be determined

Question 2 During which interval of time was the object losing speed in a positive direction?

10 < t < 11 seconds11 < t < 12 seconds4 < t < 6 seconds6 < t < 9 seconds

omit

Question 3 During which of these intervals of time was the object at rest?

none of the intervals stated17 < t < 18 seconds4 < t < 6 seconds12 < t < 15 seconds

omit

Question 4 During which interval of time was the object losing speed in a negative direction?

15 < t < 17 seconds6 < t < 9 seconds6 < t < 12 seconds11 < t < 12 seconds

omit

Question 5 If the object's initial position at t = 0 seconds was 54 meters, N, what was its instantaneous position at exactly 10 seconds?

138 meters, Ncannot be determined156 meters, N210 meters, N84 meters, N
