Question

An asteroid orbits a distant planet in an ellipse, as shown in the figure below. Astronomers estimated its speed at the periapsis to be 3630 m/s. Taking the mass of the planet equal to 7.50 x 10²³ kg, apply the law of conservation of energy to find the value of its speed at the apoapsis, marked by point O.
