In the figure, body A has a mass of 4 kg and body B has a mass of 3 kg. The mass of the pulleys and ropes is neglected. What will be the speed of an object with a mass of 3 kg 2 seconds after the moment the bodies are released? What will be the tension in the rope carrying body B? Take gravity as 10 N / kg.
HELP ASAP!!!!!!
At the neighborhood playground, your friend sits on a swing and gets pulled back by you tothe highest point that you can reach. When you let go, your friend rides the swing withoutreceiving or providing additional push. Your friend travels along an arc of 14 feet on thefirst swing (back to front). As the swing comes backwards, the length of the arc is .80 of theprevious swing. This continues: each successive arc created by swinging is .80 of theprevious swing.a. Find the length of the arc for the 5th swing (the 5th arc). Round to the thousandthsplace.b. On which swing is the length of the arc first less than 1 foot?c. Find the total distance your friend travels in all of the swings up to and including theswing in answer to letter b.
3. The principle of work and energy. A particle of mass m moves along a curve under
the action of a force F. If the speed of the particle at time t is v(t), its kinetic energy
is defined to be mv2. Prove that the change in kinetic energy in any time interval is
equal to the work done by F during this time interval.

- A pendulum consists of a small object called a bob hanging from a light cord of fixed length, with the top end of the cord fixed, as represented in Figure OQ5.6. The bob moves without friction, swinging equally high on both sides. It moves from its turning point A through point B and reaches its maximum speed at point C. (a) Of these points, is there a point where the bob has nonzero radial acceleration and zero tangential acceleration? If so, which point? What is the direction of its total acceleration at this point? (b) Of these points, is there a point where the bob has nonzero tangential acceleration and zero radial acceleration? If so, which point? What is the direction of its total acceleration at this point? (c) Is there a point where the bob has no acceleration? If so, which point? (d) Is there a point where the bob has both nonzero tangential and radial acceleration? If so, which point? What is the direction of its total acceleration at this point?

- 3. A simple pendulum consists of a pendulum bob of mass M at the end of a "mass-less" string of length L. The pendulum bob oscillates back and forth and is moving at speed v when the string is oriented at a constant angle 0 from vertical. Give answers in terms of L, 0, v, M and/or g. This is similar to the vertical circle from the Circular Motion Experiment worksheet except that we are not going in a full circle. a. Draw the free body diagram of forces acting on the pendulum bob. Include a coordinate system on your diagram showing your choice for the +x and +y directions. b. Write out Newton's 2nd law EF = mã for each direction. X: y: c.
