Problem 5: At time to = 0 a car starts moving southward from rest. It continues moving in the same direction and by time tf = 174 s has covered a distance d = 989 m. Take northward as the positive x-direction. Refer to the figure. d V south(-x) north(x) time, t,= 0 Part (a) What is the car's average speed during this period, in meters per second?
