Exercise 2: Determine the unextended length (l_0) of spring AC, if a force P = 80 lb generates the angle θ = 60 ° for the equilibrium position. Rope AB is 2 feet long. Consider the spring deformation constant as k = 50 lb / ft.
ANSWER PART D OF THIS QUESTION PLEASE
After spending an entire year together in an apartment, Grover and Elmo have decided to have some extended time apart in different parts of the state. When they get to the airport, they find out that there is a 65.000 km/hr wind that points 55.000 degrees E of S.
Grover's plane flies for 75.000 minutes before arriving at his vacation destination, which is 60.000 km W and 150.000 km S of the airport.
(a) Find the magnitude and direction of Grover's plane's velocity with respect to Earth in km/h.(b) Find the direction and magnitude of the velocity of Grover's plane with respect to the wind in km/h.(c) Draw a picture showing how the vectors add together graphically for Grover's plane during his trip. Clearly label each vector with its variable name as well as its magnitude and direction. (Hint: Make your picture large enough so that those labels are clearly visible.)(d) The plane that Elmo flew in has an airspeed of 45.000 km/hr. In what direction…

- In an equal-arm balance from the early 20th century (Fig. 31.23), an aluminum sheet hangs from one of the arms and passes between the poles of a magnet, causing the oscillations of the balance to decay rapidly. In the absence of such magnetic braking, the oscillation might continue for a long time, and the experimenter would have to wait to take a reading. Why do the oscillations decay? (a) because the aluminum sheet is attracted to the magnet (b) because currents in the aluminum sheet set up a magnetic field that opposes the oscillations (c) because aluminum is paramagnetic Figure 31.23 (Quick Quiz 31.5) In an old-fashioned equal-arm balance, an aluminum sheet hangs between the poles of a magnet.arrow_forwardExercise 2 Conservation of Linear Momentum Is Covariant Under the Galilean Transformation.
