What is the force at the lowest point of the squat (point b) if the person's mass m= 80 kg? Enter to 2 significant figures N b. What is the peak force during the push-off if the person's mass m= 80 kg? Round to the upper grid mark on the graph. Enter to 2 significant figures N For questions d-f, use the answers from the previous questions to solve for the current question. c. The take-off stage in the force-time graph occurs between the points b to c. From the plot, what is the approximate average GRF, (in terms of mg) during take-off (between b and c)? A rough estimate is fine.
