Suppose a car merges into freeway traffic on a 200-m-long ramp. If its initial velocity is 10.0 m/s and it accelerates at 2.00 m/s², how long does it take to travel the 200 m up the ramp? (Such information migh useful to a traffic engineer.) (a) Using the notation Ax for displacement, v for the final velocity, vo for the initial velocity, a for acceleration, and t for time, determine what quantities are known and what are unknown. • Enter the values of some known quantities below. • Make sure you account for the signs of the vectors using the coordinate system used in Part 1. Note: This question has 7 attempts Enter to 3 significant figures Ax= Vo m/s m/s² (b) Is the acceleration constant? = m a =
