Four locations on Earth receive sunlight at different angles. At which of the following angles will the intensity of sunlight received be the least? 0 90° 0.75° O 50° 25°​

area of focus

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
