Block A weighs 10 lb and block B weighs 3 lb. If B is moving downward with a velocity (vB)1 = 3 ft>s at t = 0, determine the velocity of A when t = 1 s. Assume that the horizontal plane is smooth. Neglect the mass of the pulleys and cords

ENGR 3341 Probability Theory and Statistics Prof. Gelb Week 3 homework solutions Textbook problems: Section 1.5, Problem 27: Consider a communication system. At any given time, the communication channel is in good condition with probability 0:8 and is in bad condition with probability 0:2. An error occurs in a transmission with probability 0:1 if the channel is in good condition and with probability 0:3 if the channel is in bad condition. Let G be the event that the channel is in good condition and E be the event that there is an error in transmission. (a) Complete the following tree diagram: P(EjG) P(G\E)
