Second Law Question
Question 1: According to Kepler's Second Law, when is a planet moving fastest in its orbit?
Question 2 (Calculation): A planet at perihelion (closest point) is 2.0 AU from the Sun and moving at 35 km/s. Using conservation of angular momentum, what is its speed at aphelion if the aphelion distance is 6.0 AU?
Formula: r₁v₁ = r₂v₂ (conservation of angular momentum)
