Question

Question 5: The two cars in Figure 5 collide at right angles in the intersection of two icy roads. Car A has a mass of 1200 kg and car B has a mass of 1600 kg. The cars become entangled and move off together with a common velocity in the direction indicated. If car A was travelling at 50 km/h at the moment of impact, compute the corresponding velocity of car B just before impact Ean 30° t ㄧㄧㄨ A-50 km/h

    Two cars collide at an intersection. Car A, with a mass of 2000 kg, is going from west to east, while car of mass 1500 kg, is going from north to south at 15 m/s. As a result, the two cars become enmeshed and move as one. As an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle of 67° south of east from the point of impact. How fast...
