8. Centripetal Forces & Gravitation / Energy of Circular Orbits / Problem 21
A space agency sends a 1200 kg space probe toward the planet Saturn. At the mission control, Saturn appears to move along the x-axis with a speed of 38 km/s. Given that initially, the probe approaches Saturn with an x-axis speed of 40 km/s (relative to the mission control on Earth), calculate the change in kinetic energy after the probe passes Saturn. (Assume that along the direction Saturn is moving, the speeds are positive.)
