An athlete completes circular track of radius 70 m in 20 seconds what will be average velocity
Answers
0 as d/t =0/20 =0 because avg velocity is total displacement divide by total time
Answer:
Concept:
The change in position or displacement (Δx) divided by the time intervals (Δt) during which the displacement happens is the definition of average velocity. Based on the direction of the displacement, the average velocity might either be positive or negative. Meters per second (m/s or ) is the SI measure for average velocity.
Explanation:
Given:
An athlete completes a circular track of a radius 70 m in 20 seconds
Radius = 70m
Time = 20 seconds
Find:
What will be average velocity
Solution:
The abbreviation for meter is m
velocity = distance/time
The distance the athlete travels is the circumference of the track.
The circumference of a circle is calculated using the following formula.
Calculate the average velocity.
Average velocity = 21.99 m/s
