An item is thrown upwards with a vertical velocity of 50 m/s, what is it's greatest height and how long is it in the air for.
I have no clue how to do that.
A body starts from rest with an acceleration of 11m/s².
What is it's velocity after 6 seconds. (I got 66 for that) and how far did it travel?
What forumla do I have to use for this?
