If Steve throws the football 50 meters in 3 seconds, what is the average speed of the football? Speed = distance / time Question 2 options: A. 16.67 m/s B. 26 m/s C. 5 m/s D. 48.9 m/s

A. 16.67 m/s

Explanation:

Speed or velocity refers to the rate of change in distance over a change in time. That is;

Speed = Distance ÷ time

Where;

Speed is in metre/seconds

Distance is in metre

Time is in seconds.

In this question, Steve throws a football 50 meters in 3 seconds. The average speed can be calculated this:

S = D/t

Where; d = 50m, t = 3s

S = 50/3

S = 16.6666666

S = 16.67m/s

c)as speed changes, wavelength and frequency change.

everything changes!
