3. A child is sitting on a swing of length L = 2 [m]. The gravitational constant is g= 10 [m/s]. Consider that the child can move its center of mass such that 1=L+r cos(@t) where r = 0.2[m]. The resulting in the equation of motion is. +2+in - sin = 0 (a) Using the numerical tools using in 2(b)-(d) determine the minimum value of @ that makes the child swing. i 1 2 [HINT: notice that r < 3.
