We'll be glad to check your answer.
the first one doesn't need any puncuation.
After the book slid from my lap and landed on my foot; I realized that I had fallen asleep.
You're right about the first sentence.
I'm not sure whether you have a comma or semicolon after foot. You need a comma there.
why do i need to add a comma there
You need a comma to separate the introductory clause from the independent clause.
