How can I delete an app from my Mac?

Episode 1184 (2:15:40)

Mike from Glendale, CA

Mike has a Kindle app on his Mac, but it won't open. Leo says to just delete it and install a new one. In his app folder, there will be a file called "Kindle." He can just drag it to the trash. Then he can download and install it again. He may also drag the icon off the dock to get rid of that as well.
