A 15.0 kg box is being pulled along level ground by a 75.0 N force that is directed at an angle of 200 above the horizontal. The coefficient of kinetic friction is 0.330. What is the acceleration of the box?

Taylor's experiment: 1. accurately measured the speed of light 2. locked together the phases of two light sources so that the interference pattern would not shift 3. showed that man's reaction time was much slower than the speed of light 4. showed that individual photons have wave characteristics
