A light string of length of 56.0 cm connects two small square blocks, each with a mass of 1.50 kg. The system is placed on a slippery (frictionless) sheet of horizontal ice and spun so that the two blocks rotate uniformly about their common center of mass, which itself does not move. They are supposed to rotate with a period of 0.750 s. If the string can exert a force of only 100 N before it breaks, determine whether this string will work.
Answer to relevant QuestionsConvert the following angles from radians to degrees: (a) π/6 rad, (b) 5π/12 rad, (c) 3π/4 rad, and (d) π rad. ACD originally at rest reaches an angular speed of 40 rad/s in 5.0 s. (a) What is the magnitude of its angular acceleration? (b) How many revolutions does the CD make in the 5.0 s? In the spin-dry cycle of a modern washing machine, a wet towel with a mass of 1.50 kg is “stuck to” the inside surface of the perforated (to allow the water out) washing cylinder. To have decent removal of water, clothes ...A man has a mass of 75 kg on the Earth’s surface. How far above the surface of the Earth would he have to go to “lose” of his body weight? An instrument package is projected vertically upward to collect data near the top of the Earth’s atmosphere (at an altitude of about 900 km). (a) What initial speed is required at the Earth’s surface for the package to ...
