You lay a mirror flat on the floor with one edge against a wall and aim a laser at the mirror. the ray reflects from the mirror and strikes the wall. the plane of the incident and reflected rays is perpendicular to the wall. the ray from the laser strikes the mirror 22.7 cm from the wall, and the reflected ray strikes the wall 35.5 cm above the mirror. find the angle of incidence of the laser ray on the mirror.

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
