Hi, welcome to TSR. It would be better that you read the guidelines and follows them in posting future problems and questions.

As you are new, I would not press for working before providing some hints. This is from Isaac Physics and it would be great if you post the link for the question for easy reference.
Direct copy and pasting the question from Isaac Physics can make the question unreadable.

The video in hint 2 from Isaac Physics actually “works out” this question from 3:59 min.
