A Planet Orbiting the Sun Has Speed V = √(GM/d)

question 49

Multiple Choice

A planet orbiting the Sun has speed v = √(GM/d) . Escape speed from the Sun is v = √v(2GM/d) , where G is the gravitational constant, M is Sun's mass, and d is the distance from the Sun. Noting that this tells us that escape speed is √2 times orbital speed, which planet would fly out of the solar system by a 1.5 increase in orbital speed?

• A)Mercury.
• B)Venus.
• C)Earth.
• D)all of the above
• E)none of the above
