there are 2 forces on a 1.0kg box, but only one is shown. For F1=30.0N, a=10.0m/s, and angle = 22.0 degrees. What is the angle made by the second force?

Abeam of light shining from water to air strikes the surface at an angle greater than 48 degrees and produces total internal reflection. if the incident beam is at a 50 degree angle what angle is the reflected beam 13 25 50 100
