The radius of Venus (from the center to just above the atmosphere) is 6050 km (6050✕103 m), and its mass is 4.9✕1024 kg. An object is launched straight up from just above the atmosphere of Venus.
(a) What initial speed is needed so that when the object is far from Venus its final speed is 5000 m/s? *(The answer for this is NOT 8891.2m/s!!!)
(b) What initial speed is needed so that when the object is far from Venus its final speed is 0 m/s? (This is called the "escape speed.")
