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 2 m/sec. The x-axis is scaled so that each square represents 1 second.

What was the cart's instantaneous speed at 12.3 seconds?

6.67 m/sec-6.67 m/sec cannot be determined-4.00 m/sec4.00 m/sec

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

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

omit

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

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