Problem 5-108 Force and Kinematics - D
Tiny Tompfind, a man of mass \(72\; kg\), jumps (from rest) from a table \(92 \;cm\) to the floor below. As he lands, he bends his knees so that he decelerates over a distance of \(35 \;cm\).
(a) What is Tiny's speed just as he hits the floor?
(b) As he decelerates, what is the magnitude of the force exerted on him by the floor?
No. While no orthogonal coordinate system is "wrong" this one is unsatisfactory since no axis is in the direction of motion.
