A crate which is able to move casts a shadow on a nearby wall due to a light source at S. The crate hasa height H and rolls toward the wall with a constant speed v, starting from the light S at time t = 0.The light S is a fixed distance d from the wall. Determine the speed at which the top of the crate'sshadow moves down the wall as a function of time, vs(t).Your answer should be an expression in terms of t, v, d and H. (Since we're interested in the speedonly, your answer should be positive.)HintHint

Solution : Let us draw the system indicating the height of the wall and the crate height and…

Consider a convex lens having a thickness d whose sides have radii of curvature R1 and R2. a. Find the 2x2 matrix describing this lensb. What is the change in focal length for the case where the two radii equal R and d =0.1R, compared to the case where the lens thickness is neglected?
P-3 Please help me with this problem very clearly with step by step explanation. Note: This problem is not very difficult if you remember to distinguish between the coordinate of the observation point and that of the integration.
The Gateway Arch, in St. Louis Missouri, is the tallest monument in the United States, at approximately 192 meters tall. A camera is 50 meters from the base of the monument and is moving along the horizontal ground away from the monument while keeping the top of the monument in view. What is the camera’s horizontal velocity when its angle of elevation (to the top of the monument) is decreasing at 0.2 radians per second?
When a man stands near the edge of an empty drainage ditch of depth 2.80 m, he can barely see the boundary between the opposite wall and bottom of the ditch as in Figure (a) shown below.

1. Roque is flying a kite along the dolomite sand of Manila Bay. If the string is 45 meters, determine the rate at which the angle of elevation is changing if the horizontal distance from him to the point directly below the kite is 13 m. Assume that he is running at a rate of 1.2 m/s; the kite is not swaying as it flies upward; and he started from rest when the kite is directly along his field of vision. A. 0.0923 rad/s B. 0.0279 rad/s C. 0.0222 rad/s D. None of these.

A camera operator is filming a nature explorer in the Rocky Mountains. The explorer needs to swim across a river to his campsite. By watching debris flowing down the river, the operator estimates that the stream is flowing at 0.625 m/s0.625 m/s . In still water, the explorer can swim at 0.735 m/s0.735 m/s . At what angle, less than 90°, with respect to the shoreline should the operator advise him to swim so that he travels directly across the stream to his campfire The water is near freezing in temperature. Typically a human can only swim in such water for about 300 s300 s (or 5 min5 min ) before hypothermia sets in. Calculate the time the explorer spends in the water if the river is 27.9 m27.9 m wide.

By watching debris flowing down the river, the operator estimates that the stream is flowing at 0.633 m/s. In still water, the explorer can swim at 0.759 m/s. At what angle, less than 90°, with respect to the shoreline should the operator advise him to swim so that he travels directly across the stream to his campfire? angle: 33.389 The water is near freezing in temperature. Typically a human can only swim in such water for about 300 s (or 5 min) before hypothermia sets in. Calculate the time the explorer spends in the water if the river is 28.3 m wide. time in the water: 81.03 S Incorrect Based on the results, what should the camera operator's decision be about the explorer's swim? Approved. He will get cold but he should be able to make it across. Sorry, but the swim must be cancelled. He will never make it across in time.
For an independent study project, you design an experiment to measure the speed of light. You propose to bounce laser light off a mirror that is 54.5 km due east and have it detected by a light sensor that is 115 m due south of the laser. The first problem is to orient the mirror so that the laser light reflects off the mirror and into the light sensor. (a) Determine the angle that the normal to the mirror should make with respect to due west. °(b) Since you can read your protractor only so accurately, the mirror is slightly misaligned and the actual angle between the normal to the mirror and due west exceeds the desired amount by 0.003°. Determine how far south you need to move the light sensor in order to detect the reflected laser light. m
