An object is moving in a circular path of radius 7m. To travel from A to B along the circumference it takes 2s. what is its average speed?

Open in App

Solution

$Speed = \frac{distance travelled}{t i m e} = \frac{half of the circumference}{t i m e}$
$= \frac{\frac{1}{2} \times 2 \times π \times r}{2}$
$= \frac{\frac{1}{2} \times 2 \times \frac{22}{7} \times 7}{2}$
$= 11 m s^{1}$
Speed and velocity can be equal for uniform motion along a straight line.
