A freely falling object requires 1.50 s to travel the last 30.0 m before it hits the ground. From what height above the ground did it fall? I have been working on this for a while and seem to be going wrong somewhere. I am unclear as to how free fall is meant here. I know that it need not refer to an object that is simply falling and can refer to any object that is experiencing gravity alone. How can I tell whether this object was thrown upward before falling? Does it make a difference? Thanks.
