Question
Richie Pulikotil walks from x = -5 m to x = +11 m in 8 seconds. Then you can say that: Richie’s Velocity is 2 m/sRichie’s Speed is 2 m/sRichie’s Average Velocity is 2 m/sRichie’s Average Speed is 2 m/s
Solution
Richie's Average Velocity is 2 m/s.
Here's why:
-
First, we need to determine the total distance Richie traveled. He started at x = -5 m and ended at x = +11 m. So, the total distance is the final position minus the initial position, which is 11 m - (-5 m) = 16 m.
-
Next, we need to determine the total time it took for Richie to travel this distance. According to the problem, it took him 8 seconds.
-
Average velocity is defined as the total displacement (change in position) divided by the total time. So, Richie's average velocity is 16 m / 8 s = 2 m/s.
The other statements are not necessarily true. Velocity is a vector quantity, meaning it has both magnitude (speed) and direction. Speed, on the other hand, is a scalar quantity, meaning it only has magnitude. In this case, we don't have enough information to determine Richie's speed or velocity at any given moment, only his average velocity over the entire 8 seconds.

Kishang Ojha is walking on the x-axis. He starts from x = 7 m and walks 8 m in the positive direction. Then he stops, turns back and walks 20 m in the negative direction and again turns around and finally walks 9 m in the positive direction. He does all this in a total time of 20 seconds. You can say that: We can only find Kishang’s average velocity, not his average speed.We can only find Kishang’s average speed, not his average velocity.Kishang’s average speed = 2.2 m/sKishang’s average velocity = -0.15 m/s
