Meriam, Kraige & Bolton — Kinematics of Particles: Problem 2_118

2/118 Cars A and B are both moving with constant speed \( v \) on the straight and level highway. They are side-by-side in adjacent lanes as shown. If the radar unit attached to the stationary police car \( P \) measures "line-of-sight" velocity, what speed \( v' \) will be observed for each car? Use the values \( v = 110 \text{ km/h} \), \( L = 60 \text{ m} \), and \( D = 7 \text{ m} \).
