When one "throws” a punch, the forearm applies force to the fist. Consider a(n) 0.75 kg fist that goes from rest to a velocity of 7.4 m/s in a time of 0.17s.
Calculate the acceleration of the fist

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
