Hey there, welcome to numerade.

For this problem, we're trying to find the expected velocity of broad c's center and the angular velocity after impact.
00:12
So to start off, we can go ahead and find our x and y components of velocity.
00:18
So vx equals 1 .5 times sine of 35 degrees, that's the angle that we're given, which is equivalent to 0 .8.
00:30
86 meters per second.
00:33
Now let's go ahead and do the same for vy.
00:36
We have 1 .5 times cosine of 35 degrees, which is equivalent to 1 .23 meters per second.
00:49
So we are going to be now using the restitution on point b.
00:57
So this here basically resembles the velocity.
01:01
And now we're going to find the restitution on point b.
01:28
All right.
01:29
So for restitution on point b, we are looking at v prime b, subscript y.
01:37
This would be negative 0 .9 times the 1 .5, giving us a restitution here of negative 1 .35 meters per second.
01:50
Now we are going to write the velocity at b.
01:55
We know at before.
02:00
We're going to write for before and after.
02:05
Starting with the before.
02:08
We have 1 .5 is equivalent to vc y plus this will be now 0 .1638.
02:25
And this here will be w...
