The lens is a concave lens

Explanation:

In concave lens, the image formed is erect. diminished and virtual. The more the distance of the object from the mirror, the more diminished the image formed will be. Concave lens are used in binoculars and telescopes and are installed before or in the eye piece to enable a clear focus.

answer; (arch); good luck

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
