Two cars collide at an intersection on a horizontal road. One car, with a mass of 1.11 x 10' kg, is initially moving east with a speed of 8.14 m/s and the other car, with a mass of 1.74 x 10" kg, is initially moving north with a speed of 5.02 m/s. The two cars stick together after the collision. (a) Calculate the speed of the cars immediately after the collision. 4.0 19.4 x m/s (b) Find the angle at which the cars move after the accident. The angle is measured counterclockwise from the east direction. 4.0V 68,5
