suppose a classmate conducts a similar investigation using a different spring. the classmate tells you their trendline equation for this different spring is
y = 0.30*x + .731
the classmate indicates an unknown mass was attached to their spring and it stretched a length of 60 cm.
the classmate concludes the unknown mass must equal 150 g and asks if you agree.
in the space below, construct a short paragraph (5-6 sentences) indicating if you agree or disagree with the classmate's conclusion that the unknown mass is 150 g. your paragraph must include a scientific explanation why you agree or disagree with the mass of 150 g. for example, you could discuss the slope of the line and how it's used to determine the object's mass.
