La velocidad de la luz en un material es del 67% del valor de la velocidad de la luz en el vacío. Considerando lo anterior, determine el valor del ángulo refractado si el ángulo de incidencia es de 34° y proviene de un material con índice de 1,73

d. learned preferences i believe is your answer

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

there are no atoms
