Spiderman uses his spider webs to save a runaway train moving about 50 km/h , (Figure 1). His web stretches a few city blocks (400 m ) before the 104-kg train comes to a stop. Assuming the web acts like a spring, estimate the effective spring constant. Express your answer to one significant figure and include the appropriate units.
