(b) Table Question 3 presents data collected during the stance phase of gait. Given that y=40mm, use the information in the table to determine: i. the ankle moment ii. the knee moment

Help!!! Please answer all correctly!!! Please

Suppose that over the next T = 30 seconds the driver can choose from the three possible force profiles, F(t), shown above, where P = 2000 N is the same maximum force reached during each profile. Write down an expression for each of the force profiles F1(t), F2(t), F3(t) as a function of the magnitude P and time. You can construct the force profiles from a combination of Heaviside functions and ramps (straight lines) with appropriate slope.
