Plan an investigation to determine how the mass of a sumo wrestler affects the force needed to move them. Finley and Jasmin are curious about this. Which of the following would be the best approach?

• Measure the force needed to move wrestlers of different masses using a force sensor.

• Observe sumo matches and record the outcomes.

• Interview sumo wrestlers about their training routines.

• Calculate the average weight of sumo wrestlers.
