Lee rode a skateboard to school. His velocity changed from 2 m/s east to 5
Marta_Voda [28]

Answer:

Option B. 3 m/s east

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 2 m/s east

Final velocity (v) = 5 m/s east

Time (t) = 6 s

Change in velocity =?

We can obtain the change in Lee's velocity as illustrated below:

Initial velocity (u) = 2 m/s east

Final velocity (v) = 5 m/s east

Change in velocity =?

Change in velocity = Final velocity (v) – Initial velocity (u)

Change in velocity = v – u

Change in velocity = 5 – 2

Change in velocity = 3 m/s east

Thus, the change in Lee's velocity is 3 m/s east
