Re: ISAT previous year question paper
The Indian Institute of Space Science and Technology does conduct ISAT entrance exam for invites application for B Tech student. Here I am providing you old year paper of ISAT. 1. A projectile is fired at an angle 60◦ with some velocity u. If the angle is changed infinitesimally, let the corresponding fractional changes in the range and the time of flight be x and y, respectively, Then y is (A) 2 3x (B) −2 3x (C) 2x (D) −2x 2. A ball is dropped down vertically from a tall building. After falling a height h it bounces elastically from a table inclined at an angle θ and hits a wall at a distance d from the point of earlier impact horizontally, then (A) θ = (1/2) sin−1(2d/h) (B) θ = (1/2) tan−1(d/h) (C) θ = (1/4) sin−1(d/h) (D) θ = (1/2) tan−1(2d/h) For more paper visit here: http://studychacha.com/discuss/36150...ions-math.html |
