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.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
