In a controlled automobile collision, a 44-kilogram crash-test dummy moving at 15 meters per second is brought to rest by a seat belt during a 0.10-second time interval. What is the magnitude of the average force exerted on the dummy during this interval

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
