A flashlight is used to propel an 85 kg reflective load in space. If the flashlight emits 1W of light in a parallel beam for 1 hour, and the entire beam falls on the surface of the load, find how far the load will have moved at the end of the hour. Assuming it started at rest. (Hint: the force, mass, and acceleration are related through F=m*a; you should also use the physics equation relating position, velocity, and acceleration).
The intensity of light I through a lake at a depth of x meters is given by the following formula.
dI/dx = (-2.31)I
a.) At what depth is the intensity of the light half that of the intensity at the surface, I00?
b.) At 5 meters deep, what is the intensity of the light as a fraction of I0?
c.) How many meters deep will the intensity of light be 1 percent of the intensity of the light at the surface?
Remember that the depth at the surface is x = 0.

An object is to be placed at a point P on a line l, parallel to the line joining the light sources and at a distance d meters from it (see the figure). We want to locate P on, so that the intensity of illumination is minimized. We need to use the fact that the intensity of illumination for a single source is directly proportional to the strength of the source and inversely proportional to the square of the distance from the source. a) Find an expression for the intensity l(x) at the point P. b) If d = 5m, use graphs of l(x) and l'(x) to show that the intensity is minimized when x = 5m, that is, when P is at the midpoint of l. c) If d = 10m, show that the intensity (perhaps surprisingly) is not minimized at the midpoint. d) Somewhere between d = 5m and d = 10m there is a transitional value of d at which the point of minimal illumination abruptly changes. Estimate this value of d by graphical methods. Then find the exact value…arrow_forward
