From mech2020 lecture notes
A KMB 11 bus is traveling east at the
constant speed of 36 km/h. As the KMB 11 bus crosses the intersection, a KMB 6 bus starts from rest at a bus stop 35 m north of the intersection and moves south with a constant acceleration of 1.2 m/s2. Determine the position, velocity, and acceleration of KMB 6 relative to KMB 11, 5 s after KMB 11 crosses the intersection.
