Is the U sound in bus a long or short vowel sound?

Here's why:

* Short vowel sounds are typically quick and sharp. They are often represented by a single vowel letter in the spelling.

* Long vowel sounds are typically drawn out and can be represented by a single vowel letter followed by a silent "e" or a double vowel.

The "u" in "bus" is a single vowel letter and the sound is quick and sharp.
