Answer #1

Rate of change of momentum is the force on the comet. At the given position, the force on the comet will be the gravitational force by the Sun. And the direction of this force will be represented by an arrow towards the Sun. Hence the correct option will be A.

    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...

    A comet orbits the Sun and loses mass at a constant rate of 30,000kg/s. The only force acting on the comet is the gravitational force. a) From the definition of torque in terms of angular momentum, torque=dL/dt, show that dI/dt=-alphaI/omega (alpha= angular acceleration, omega=angular velocity) b) The quantity omega/omega(with a dot on it), where (omega with a dot on it=domega/dt) is a natural time scale for the system's change in angular frequency (to see this, think about the units). Approximating...
