Hi there.
00:02
So for this problem, we're told that an object is orbiting uniformly around a center, and it has a radius that is given, and that radius is equal to one kilometer.
00:13
We know that one kilometer in meters is equal to 1 ,000 meters, and undergoes an angular displacement, and that angular displacement is equal to one degree in an interval of time that is equal to 0 .1 seconds.
00:35
So the question is, what is the tendential velocity of this object? so that's what we need to obtain the tendential velocity.
00:44
So the first thing that we need to do is to transform the angular displacement from degrees to radiance.
00:51
We know that pi radiance equals to 180 degrees.
00:56
So from this, we obtain an angular displacement of 0 .0 .1 ,745 radiance.
01:18
Now, we know that the angular velocity is equal to that angular displacement divided by the time.
01:28
So that will be the value that we just obtain radiance divided by the interval of time that we are given for this case, which is 0 .1 seconds...
