Land west of the San Andreas fault in southern California is moving at an average velocity of about 6 cm/y northwest relative to land east of the fault. Los Angeles is west of the fault and may thus someday be at the same latitude as San Francisco, which is east of the fault. How far in the future will this occur if the displacement to be made is 590 km northwest, assuming the motion remains constant?

(a) A jet airplane flying from Darwin, Australia, has an air speed of 260 m/s in a direction 5.0° south of west. It is in the jet stream, which is blowing at 35.0 m/s in a direction 15° south of east. What is the velocity of the airplane relative to the Earth? (b) Discuss whether your answers are consistent with your expectations for the effect of the wind on the plane's path.
Galileo thought about whether acceleration should be defined as the rate of change of velocity over time or as the rate of change in velocity over distance. He chose the former, so lets use the name vroomosity for the rate of change of velocity over distance. For motion of a particle on a straight line with constant acceleration, the equation v = vi + at gives its velocity v as a function of time. Similarly, for a particles linear motion with constant vroomosity k, the equation v = vi + kx gives the velocity as a function of the position x if the particles speed is vi at x = 0. (a) Find the law describing the total force acting on this object of mass m. Describe an example of such a motion or explain why it is unrealistic for (b) the possibility of k positive and (c) the possibility of k negative.
A river flows with a steady speed v. A student swims upstream a distance d and then back to the starling point. The student can swim at speed c in still water. (a) In terms of d, v, and c, what time interval is required for the round trip? (b) What time interval would be required if the water were still? (c) Which time interval is larger? Explain whether it is always larger.

Assign.#(2)... Analysis of a Power Law Suppose we are told that the acceleration (a) of a particle moving with uniform speed (v) in a circle of radius (r) is proportional to some power of r, say (), and some power of (v), say (V™).

Two siblings, Kaeya and Diluc, decided to take a walk around Mondstadt, following its perimeter guarded by walls. For those who haven't seen Mondstadt, you can imagine it as a city of walls with beautiful German architecture. Let's roughly assume that the walls are encircling it in a perfect circle. Both Kaeya and Diluc started at the front of the huge city gate (marked at 0 degrees), and they walk separately, away from each other. Assuming that radius of the circular city of Mondstadt to be 500 m, and the constant walking speed of both siblings to be 0.5 m/s, how long until the siblings achieve the greatest separation distance between them? 3.
