Nazima is fly fishing in a stream. The tip of her fishing rod is 1.8 m about the surface of the water and the fly at the end of the string rests on the water 3.6 m away and 2.4 m from a point directly under the tip of the rod. Assuming that her string [...]

An artificial satellite of mass m is moving in circular orbit at a height equal to the radius R of the earth. Suddenly due to internal explosion the satellite breaks into two parts of equal pieces. One part of the satellite stops just after the explosion. The increase in the mechanical energy of the system [...]

Two satellites S1 and S2 are revolving around the earth in coplanar concentric orbits in the opposite sense. At t=0, the position of satellites are shown in the diagram. The periods of S1 and S2 are 4h and 24h, respectively. The radius of orbit of S1 is 1.28 × 10^4 km. For this situation, mark [...]
