In order to serve as an effective representation of an object, scale models must These are the choices
A maintain the relative values of size of the object being modeled.
B.
deviate from the appearance of the object being modeled.
C.
be able to perform the same function as the object being modeled.
D.
exaggerate the size of important aspects of the object being modeled.

your answer is c! hope this : )

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

+15-35=-20

going in opposite directions
