Constant Velocity: Velocity-Time Graphs

Directions: On this worksheet you will practice working with velocity-time graphs for "constant velocity."

Question 1 The y-axis, representing velocity, is scaled so that each square (vertical division) represents 4 m/sec. The x-axis is scaled so that each square represents 1 second.

What was the cart's instantaneous speed at 14.6 seconds?

0.77 m/sec cannot be determined-8.00 m/sec-0.77 m/sec8.00 m/sec

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

4 < t < 6 seconds10 < t < 11 seconds11 < t < 12 seconds6 < t < 9 seconds

omit

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

17 < t < 18 seconds12 < t < 15 seconds4 < t < 6 secondsnone of the intervals stated

omit

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

11 < t < 12 seconds6 < t < 12 seconds6 < t < 9 seconds15 < t < 17 seconds

omit

Question 5 If the object's initial position at t = 0 seconds was 49 meters, N, what was its instantaneous position at exactly 10 seconds?

56 meters, N105 meters, Ncannot be determined104 meters, N153 meters, N
