15. A rock of mass 1.0 kg is dropped from a height of 10 m. What will be its velocity just before it strikes the ground? What if the height is 100 m? (Neglect air friction)
PS: we are given a set of equations to use in the homework. They are in the screenshot below. Also, pretty sure that we need the equation v=sqrt(2gh) , though it is not in the list of equations provided to us.
