The car has an initial speed v0 = 20 m>s. If it increases its speed along the circular track at s = 0, at = (0.8s) m>s 2 , where s is in meters, determine the time needed for the car to travel s = 25 m.

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)
