7.how large is the moon compared to earth? a. about the same diameter as earth b. about one-half the diameter of earth c. about one-fourth the diameter of earth d. about one-eighth the diameter of earth

f is prop to m1xm2 double m1 double force

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
