The weight of a football player is 680 N. What is his mass? g = 9.8 m/s2​

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

snell's law

refractve index = sin incidence / sin refraction

did yall get answers for this yet
