Which of the following is not one of the observed characteristics of our solar system?
all planets go in the same circular direction
all planets look as though they lie along a flattened circular plane or disk
the sun and planets rotate in the same direction
all moons orbit planets in a counterclockwise direction

The answer is: all moons orbit planets in a counterclockwise direction

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
