- 6.Integrated Concepts - Frozen waste from airplane toilets has sometimes been accidentally ejected at high altitude. Ordinarily it breaks up and disperses over a large area, but sometimes it holds together and strikes the ground. Calculate the mass of 0C ice that can be melted by the conversion of kinetic and gravitational potential energy when a 20.0 kg piece of frozen waste is released at 12.0 km altitude while moving at 250 m/s and strikes the ground at 100 m/s (since less than 20.0 kg melts, a significant mess results).How much work is needed to lift a bag of groceries that weighs 250N to a height of 4m? A. 1000 Calorie B. 1000 J C. 1000 N D. 1000 kJ
- Learning Goal: To learn and practice the geometry skills necessary for complex reflection setups. The law of reflection has the very simple form Oreflected, Vincident = where incident is the angle between the normal and the incident ray and reflected is the angle between the normal and the reflected ray. Although the law itself is easy to use, many realistic situations involve successive reflections from multiple surfaces. The law of reflection does not become any more complicated in such cases, but the geometry of the rays does become complicated. Consider the case of light shining onto a mirror, which is attached to another mirror at some angle a, as shown in the figure (Figure 1). In this problem, we will find the angle at which light leaves the arrangement of two mirrors. Figure 1 of 2 > Part A If the light strikes the first mirror at an angle 0₁, what is the reflected angle 02? Express your answer in terms of 0₁. 0₂ = 0₁ Submit Part B Correct Previous Answers Now, find the angle…assume adibatic. other solutions are wrong
