Suppose that a person gets hit by a bus moving at 30 mi/h with a 58,000 lbs of force in the direction of motion. If the mass of the bus is 40,000 lbs and persons is 150 lbs and if the impact lasts only 0.007 seconds. A. Determine the speed of the person at the end of the impact and convert to mi/h.

B. What is the expected speed of the person at the end of the impact and does your finding agree with that expectation?

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
