Q1. A person whose eyes are H = 1.64 m above the floor stands L = 2.3 m in front of a vertical plane mirror whose bottom edge is 38 cm above the floor. What is the horizontal distance x to the base of the wall supporting the mirror of the near point on the floor that can be seen reflected in the mirror?

Q2. A 39.0- body is moving in the direction of the positive x axis with a speed of 361 when, owing to an internal explosion, it breaks into three pieces. One part, who's mass is 7.5, moves away from the point of explosion with a speed of 475 along the positive y axis. A second fragment, who's mass is 3.5, moves away from the point of explosion with a speed of 485 along the negative x axis. What is the speed of the third fragment? Overlook effects due to gravity.
