NEETPhysicsMotion in One Dimension

In the x-t plot of a particle's one-dimensional motion (Figure 2.14), three different equal intervals of time are shown. In which interval does the particle have the greatest average speed, and in which interval does it have the least average speed? Additionally, what is the sign of the average velocity for each of these intervals?

Options

  1. AThe greatest average speed is in Interval 3, and the least average speed is in Interval 2. The average velocit
  2. BThe greatest average speed is in Interval 2, and the least average speed is in Interval 1. The average velocit
  3. CThe greatest average speed is in Interval 1, and the least average speed is in Interval 3. The average velocit
  4. DThe greatest average speed is in Interval 3, and the least average speed is in Interval 1. The average velocit

Correct answer

A. The greatest average speed is in Interval 3, and the least average speed is in Interval 2. The average velocit

Step-by-step solution

Correct Option is : (A) The greatest average speed is in Interval 3, and the least average speed is in Interval 2. The average velocity is positive in Intervals 1 and 2, and negative in Interval 3.
