A90-g bead is attached to the end of a 60-cm length of massless string. the other end of the string is held at point o, which is 200 cm above the floor, and the bead is swung counterclockwise at a constant speed in a vertical circle. the tension in the string when the bead is at the very bottom of the circle is 2.2 n. while the bead is in motion, a very sharp knife is inserted to cut the string directly below point o. how far to the right of the center of the circle does the bead hit the floor?

answer; (arch); good luck

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
