Question

A bug completes one lap along the edge of a circular planter of radius 18.3 cm in 13.81 s. answer to the nearest thousandth in units of meters per second

Answer 1

Answer:

Speed of the bug is 0.0832 m/s.

Explanation:

We have,

Radius of the circular planet is 18.3 cm or 0.183 m and time taken by the bug to complete one lap is 13.81 s.

It is required to find the speed of the bug in the circular path. It is given by the displacement in one lap divided by time taken. So,

$v=\dfrac{d}{t}\\\\v=\dfrac{2\pi r}{t}\\\\v=\dfrac{2\pi \times 0.183 }{13.81}\\\\v=0.0832\ m/s$

So, the speed of the bug is 0.0832 m/s.
