You run to your girlfriend's house and announce that you were running at a rate of 15 miles per hour. she knows this is not true because she knows
a)how far it is and in what direction.
b)the direction you traveled and how long it took you to get there.
c)when you left and when you arrived.
d)how long it took you to get there and the distance between your house and hers.

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
