Question

comets travel around the sun in elliptical orbits with large eccentricities. If a comet has speed 1.0 x 104 m s when at a distance of 29×10 . m from the center ofthe sun, what s its speed when at a distance of 6.0 x1010 m? 0/1 points| Previous Answers My Notes Suppose that a binary star system consists of two stars of equal mass. They are observed to be separated by 375 million kilometers and take 3.50 Earth years to orbit about a point midway between them. What is the mass of each? M1 м,

Answer #1

Solution)

Acc to Conservation of Energy

V2=sqrt(v1^2 + 2GM (1/d1 - 1/d2))

V2= sqrt((1*10^4)^2 + 2*(6.67*10^-11)*(1.99*10^30)(1/6*10^10 - 1/ 2.9*10^11))

V2= 1000 m/s

    A comet moves about the Sun in an elliptical orbit, with its closest approach to the Sun being about 0.620 AU and its greatest distance from the sun being 35.5 AU (1 AU = the Earth-Sun distance). If the comet's speed at closest approach is 54.0 km/s, what is its speed when it is farthest from the Sun? (The gravitational force exerted by the Sun on the comet is parallel to the moment arm, so exerts no torque. Therefore, angular...
