(part 2 of 2) An Introductory Projectile Motion Problem with an Initial Horizontal Velocity
Now that we have dropped the ball into the bucket, we can determine the final velocity of the ball right before it strikes the bucket. Don't forget that velocity is a vector and has both magnitude and direction. Yep, component vector...

What’s a QR Code And How Is It Different From A Barcode?
While a barcode only holds information in the horizontal direction, a QR code does hold information in both horizontal and vertical directions. Due to this, a QR code holds hundreds of times more information than a barcode.

Basic statics problem finding reactions of pin supports
This video shows how to find the magnitudes of reaction forces of pins. A general approach to this question is to 1) draw a FBD 2) use Mtotal = 0 and Ftotal =0 3) solve the algebra. A few things to note are: Pin supports apply external...
