Meriam, Kraige & Bolton — Kinetics of Particles: Problem 3_164

3/164 Car B is initially stationary and is struck by car A moving with initial speed \(v_1 = 30 \text{ km/h}\). The cars become entangled and move together with speed \(v'\) after the collision. If the time duration of the collision is 0.1 s, determine (a) the common final speed \(v'\), (b) the average acceleration of each car during the collision, and (c) the magnitude R of the average force exerted by each car on the other car during the impact. All brakes are released during the collision. Given Data: Mass of car A, \(m_A = 1800 \text{ kg}\) Mass of car B, \(m_B = 900 \text{ kg}\) Initial velocity of car A, \(v_1 = 30 \text{ km/h}\) Initial velocity of car B, \(v_B = 0\) Collision duration, \(\Delta t = 0.1 \text{ s}\)
