Question

1. a housefly is flying around a baseball field. at one point, the insect is flying north at 2.3 meters per second. at that instant, a ball is flying past the insect, also going north, at a velocity of 34.0 meters per second. from the flys frame of reference, what was the velocity of the ball?

36.3 m/s
-36.3 m/s
34 m/s
31.7 m/s

Explanation:

Step1: Determine the relative velocity formula

The formula for relative velocity \(v_{rel}=v_{ball}-v_{fly}\) when both are moving in the same direction.

Step2: Substitute the given values

Given \(v_{ball} = 34.0\ m/s\) (velocity of ball) and \(v_{fly}=2.3\ m/s\) (velocity of fly). Then \(v_{rel}=34.0 - 2.3\).

Step3: Calculate the result

\(v_{rel}=31.7\ m/s\)

Answer:

31.7 m/s
