Here is my question
A meteoroid is moving towards a planet. It has mass m = 0.34 × 109 kg and speed v1 = 2.6 × 107 m/s at distance R1 = 1.6 × 107 m from the center of the planet. The radius of the planet is R = 0.22 × 107 m. The mass of the planet is M = 9.6 × 1025 kg. There is no air around the planet.
Enter an expression for v, the meteoroid's speed at the planet's surface, in terms of G, M, v1, R1, and R.
Calculate the value of v in meters per second.
