Help me fill in the tablenand answer the question ( show me the proper calculation)

PLEASE ANSWER COMPLETE WITH BRIEF EXPLANATION IN EVERY STEP. Motor A pulls the cord with an initial speed of 8.14 ft/s. The acceleration of pull is illustrated in the graph below. On the other hand, block C is moving to the right at a constant speed of vc = 2 ft/s. a) Determine the velocity of block B when t = 6s. b) Determine the velocity of point D relative to block B at this instant. Please show your reference point (1 only) and the positions of all variable points considered relative to the reference point.
