In competition, an athlete threw a flying disk 139 meters through the air. while in flight, the disk traveled at an average speed of 13.0 m/s. how long did the disk remain in the air?

Time, t = 10.69 seconds

Explanation:

Given that,

Average speed of the disk, v = 13 m/s

The athlete threw a distance through the air, d = 139 meters

We need to find the time the disk remains in the air. Let t is the time taken. The average speed of the disk is given by :

t = 10.69 seconds

So, the disk remains in the air for 10.69 seconds. Hence, this is the required solution.

answer: electrons

it doesn't. it was imagined up in the middle ages.
