In which situation is work being done? А. No force is applied.
B. The force does not result in displacement.
C. The force and displacement are perpendicular to each other.
D. The force and displacement are in the same direction.

answerscientific theory;

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

the awnser is d you right bro                      

just copy what u wrote and paste and search in google
