A stick figure of mass running at speed grabs a light rope that hangs from a ceiling of height H and swings to a maximum height of In another room with a ceiling of height H/2, a second stick figure with mass running at the same speed grabs a light rope hanging from the ceiling and swings to a height of . How does the maximum height reached by the two stick figures compare and why?
The first stick figure swings to a higher height since he swings from a higher rope.
The second stick figure swings to a higher height since he has more mass.
The two stick figures reach the same height, because the length of the second rope offsets the mass of the second stick figure.
Both stick figures swing to the same height because they have the same initial speed.
