Description | A small plane is traveling horizontally with a velocity of two hundred kilometers per hour at a distance of eighty meters above the surface of the earth. At the same time, a car is traveling on the ground in front of the plane at a velocity of one hundred fifty kilometers per hour. We want to calculate at what angle with respect to the horizontal the car should be (in the planes sights) when the package is dropped. In order to simplify this problem, we need to choose a reference frame in which the car is stationary and the plane is moving. Therefore, we need to find the relatively velocity of the plane with respect to the stationary car. Once we find that, we can calculate the distance that package will travel to get to the car. Using this information, we can then set up a triangle and use one of the trigonometric functions to find the angle with respect to the base of the triangle. Note that the height of the triangle is simply the height that the plane is traveling above the surface. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
