Solution Summary: The author calculates the total number of ancestors that an individual has going back 12 generations.
To calculate:The total number of ancestors that an individual has going back 12 generations, if first generation have 2 parents, second generation have 4 grandparents, third generation have 8 great grandparents. The terms of the sequence 2,4,8,16,.... give the additional number of ancestors for each generation back on time.
Trolley of the overhead crane moves along the bridge rail. The trolley position is
measured from the center of the bridge rail (x = 0) is given by x(t) = 0.5t^3-6t^2+19.5t-14 : 0 <= t <= 3 min. The
trolley moves from point A to B in the forward direction, B to C in the reverse direction and C to D again in the
forward direction.

Total masses of the trolley, hook block, and the load attached to the hook block are 110 kg, 20
kg, and 150 kg. Damping coefficient, D, is 40 kg/s.
What is the total amount of energy required from the trolley motor to move the system
