( IM IN A HURRY) if u can help

compass can be used day and night, cloudy or sunny

wavelength divides in half and speed stays the same.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

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
