An athlete pulls handle a to the left with a constant force of p = 125 n. knowing that after the handle a has been pulled 30.25 cm its velocity is 3.2 m/s, determine the mass of the weight stack
b. (round the final value to two decimal places.)

You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 1515 lb and was traveling eastward. car b weighs 1125 lb and was traveling westward at 44.0 mph. the cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . how fast (in miles per hour) was car a traveling just before the collision? (this problem uses english units because they would be used in a u.s. legal proceeding.)
