Question

A trucker drives along a straight highway for 0.25 h with a displacement of 16 km south. What is the trucker’s average velocity?

helping me would b a big help ;)

Answer 1

The trucker’s average velocity who drives the truck along  a straight highway is 64 km/h in south.

What is average velocity?

Average velocity of a body is the ratio of displacement of a body in the given time. In case of average velocity, the displacement of the body is the same for each interval of time.

Average velocity can be calculated with the following formula.

$\overline v =\dfrac{\Delta x}{\Delta t}$

Here, Δx is the displacement and Δt is the change in time. The average velocity can be positive or negative.

A trucker drives along a straight highway for 0.25 h with a displacement of 16 km south.

The displacement of the truck is 16 km in the south direction, and change in time to cover this distance is 0.25 hours. Thus, the average velocity of the truck is,

$\overline v =\dfrac{16}{0.25}\\\overline v =64 \rm\; km-h^{-1}$

Hence, the trucker’s average velocity who drives the truck along  a straight highway is 64 km/h in south.
