1) A man and his son are standing at the edge of a cliff. They both pick up very similar rocks and throw them horizontally off the cliff. The man's rock
travels twice as far from the base of the cliff as the rock that the boy threw. If they both threw their rocks at the same time and from the same height,
which one hits the ground first?
the boy's rock.
the man's rock.
they would land at the same time.
