I have to do this problem but I have no idea how to interpret the data! Can somebody pleeeeeeeeeease help me?:wave:
An object is thrown upward from a platform above ground. At various times post release, its height above ground is noted.
Ignoring air resistance, wind, etc, answer the following:
How fast was the initial velocity and how high was the platform? The greatest value in the height column is 824. Is this the maximum height the object reached, or did it go higher (explain)? When will it hit ground and how fast will it be going then?
