The planet Mercury has a mass of 3.30×1023 kilograms (kg) and a radius of 2440 kilometers (km). The universal gravitational constant is G = 6.67 × 10−11 Nm2/kg2.
A) If a is ball is launched upwards from the surface of Mercury with an initial speed of 2.15 kilometers per second (km/s), what height maximum height above the surface will it reach before falling back down? Give your answer in units of kilometers (km). Assume that the total mechanical energy of the ball is conserved.
B) What is the escape speed of Mercury? Give your answer in units km/s.
The law of universal gravitation says that there is a force between two
objects in the universe. Can there ever be a physical instance when the
two objects will never have an influence on each other?
Hint: look at the equation that relates force, mass, distance, and the
gravitational constant G:
Gxm, xma
F =
O No, no matter how far apart they are, there will always be some tiny force
acting between the two.
O No, Since the distance between two objects can never be zero.
All listed answers here are correct.
O No, they will always influence each other. You cannot divide by zero.
