1. A uniform horizontal beam has a mass of 13.1 kg. As you see below, the cable makes an angle of 45 degrees with a vertical pole. The beam's right end is connected to the light (essentially mass-less) cable making a 45-degree angle with the beam. The beam's left end is hinged at pivot A on the rigid, fixed pole. The left end of the cable is also attached to the pole. See figure. Show all work. (a) (b) What is the tension T in the cable? What is the horizontal component of force FH exerted by pivot A on the beam? (c) What is the vertical component of force Fv exerted by pivot A on the beam ? (d) Assuming the beam length is 1.1 m, suppose a vandal severs the cable such that the tension becomes zero. Consider the moment just after the cable is cut and the beam is still in a horizontal position. At that instant, what is the magnitude of the torque (about pivot A) exerted by the gravitational force? What is the magnitude of the beam's angular acceleration about point A at this instant? POLE A CABLE 45

The graph above represents the data from Activity 3 in this week's lab describing the position of a moving cart as a function of time. The equation for the best-fit line for this position vs. time graph is y = 3.9609x + 0.1739. What distance would you expect the cart to travel if you let it move for 53 seconds?

Velocity Addition: A spaceship passes Earth at a steady forward speed of 70% the speed of light. How fast relative to the ship must the spaceship launch a shuttlecraft in the forward direction so that it will be moving away from Earth at 98.7% the speed of light?
Please answer all questions fully. Thank you. 1. You are in a windowless car of a train that is either stationary or moving at a constant velocity with respect to Earth. Is there any experiment you can do in the train to determine whether you are moving? 2. You are travelling in a train that is slowing down upon approaching the station. You throw a heavy ball, aiming it directly at the ceiling above your chair. Relative to you, where will the ball fall? 3. Is there a situation where 2 events that occur at the same time for one observer can be simultaneous to a second observer moving with respect to the first? Explain your answer.
Please use the information given to answer parts A and B. Thank you in advanced!
