Lois Lane falls for 10s. Superman catches her, bringing her to a halt in 10cm. Lois has a mass of 50kg. How much force does superman inflict on her spine? A) 500N

B) 2500000N

C) 25000N

D) Can't solve without superman's mass

show your work please

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
