Question

A dancer demonstrating dance steps along a straight line. The position time graph is given. Find the average velocity for the dance step depicted by AB.

• A. $1m{s}^{-1}$
• B. $1.33m{s}^{-1}$
• C. $2.75m{s}^{-1}$
• D. $0m{s}^{-1}$

Answer 1

The correct option is D $0m{s}^{-1}$

For the dance step depicted by AB :
Path length $=$ 0;
Displacement $=$ 0
Time taken, t $=$ 1 s
Average velocity $=\frac{displacement}{timetaken}$
$=\frac{0}{1}=0$
