Q. By accident, a large plate is dropped and breaks into three pieces. The pieces fly apart parallel to the floor, with v1 = 2.80 m/s and v2 = 1.60 m/s. As the plate falls, its momentum has only a vertical component, and no component parallel to the floor. After the collision, the component of the total momentum parallel to the floor must remain zero, since the net external force acting on the plate has no component parallel to the floor.find the masses of pieces 1 and 2.

Q. A train on a straight, level track has an initial speed of 40.0 km/h. A uniform acceleration of 1.50 m/s squared is applied while the train travels 210m. what is the speed of the train at the end of this distance? How long did it take for the train to travel the 210m?
