The v-t plot of a moving object is shown in the figure. The average velocity of the object during the first 10 seconds is:
Correct answer: A. 0 m/s
- A. 0 m/s
- B. 25 m/s
- C. 5 m/s
- D. 2 m/s
Explanation
Step 1: Understand the given v-t plot and the question. The v-t plot shows the velocity of an object over time. We need to find the average velocity during the first 10 seconds. Step 2: Calculate the displacement from the v-t graph. The area under the curve from 0 to 5 seconds is (1/2) x 5 x 5 = 12.5 m. The area under the curve from 5 to 10 seconds is (1/2) x 5 x (-5) = -12.5 m. Total displacement = 12.5 m - 12.5 m = 0 m. Step 3: Calculate the average velocity. Average velocity = Total displacement / Total time = 0 m / 10 s = 0 m/s.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
