What is the specific angular momentum of an elliptical orbit, if the flight path angle of the satellite in orbit at an instant is 15°? The satellite is travelling at a velocity of 10.7 km/s at the same instant and is parked at an altitude of 7048 km measured from earth’s center.

Correct Answer: 72,876.32 km2/s
Given, Velocity of satellite (v) = 10.7 km/s Flight path angle (γ) =15° Satellite distance (r) = 7048 km Tangential velocity (vt) = vcos(γ) = 10.7*cos(15°) = 10.34 km/s Specific angular momentum (h) = rvt = 7048*10.34 = 72,876.32 km2/s

Arun and Amit started walking from two different points 'A' and 'B' respectively.Arun walks 2 kms North and turns to the East and walks 3 kms and again turns to North walks 4 kms and finally turns to East and Walks 5kms to reach point 'C'. Similarly, Amit walks 2 kms North and turns to west and walks 3 kms and finally turns to North, walks 4 kms and meets Arun at point 'C'. What is the distance between Arun and Amit's starting points?

Consider the following information and answer questions based on it. Six cars S, T, V, W, X and Y are parked in a parking lot, in a random order, from left to right, such that - A.T is parked on the extreme right. B.V is parked to the immediate right of Y and is one car away from W. C.X is to the immediate left of T and is three cars away from S. Which car is parked to the immediate left of X?

What is the specific angular momentum of an Iridium satellite if the orbit is in an elliptical orbit that has a semi-major axis and eccentricity of 46,000 km and 0.85 respectively. Gravitational parameter of earth is 398,600 km3/s2?
