Answer:
mass of sinope is 6 * 10¹⁶ kg
the ball pitcher can throw the ball fast enough to escape Sinope's gravity
Explanation:
mass of sinope m = 6 * 10¹⁶ kg
radius r = 18000 m
the escape velocity v = [tex]\sqrt{\frac{2GM}{r} }[/tex]
v = [tex]\sqrt{\frac{2 * 6.67 * 10^-^1^1 * 6 * 10^1^6}{18000} }[/tex]
v = 21.1 m/s
v is less than 45 m/s
the ball pitcher can throw the ball fast enough to escape Sinope's gravity
