hi
Im stuck on how to do this question ...can anyone give me any hints :
The American artificial planet Pioneer IV reached its closest approach to the sun 91.7 million mi on march 17 1959.
At aphelion it will be 106.1 million mi from the sun.
What is:
a.) the speed at which it passed perihelion
b.) its sidereal period
thanks
Roger
