Chapter 2: Q8PE (page 82)

Land west of the San Andreas fault in southern California is moving at an average velocity of about 6cm/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 is590km northwest, assuming the motion remains constant?

Short Answer

Expert verified

9.83x106 y

Step by step solution

01

Given Data

  • Speed of the drift=6 cm/y=0.06x10−3 km/y.
  • Distance of the drift =590 km .
02

Speed of the drift

How much distance is traveled in a given time can be used to determine the speed.

Speed does not need a direction to express it. It is a scalar quantity.

Time=DistanceSpeed

Substituting values in the above expression, we get:

T=590 km0.06×10−3 km/yT=9,833,333.33 y

Hence in 9.83x106 y, they will be 590km apart from each other.

In 1967, New Zealander Burt Munro set the world record for an Indian motorcycle, on the Bonneville Salt Flats in Utah, with a maximum speed of\({\bf{183}}.{\bf{58}}{\rm{ }}{\bf{mi}}/{\bf{h}}\). The one-way course was\({\bf{5}}.{\bf{00}}{\rm{ }}{\bf{mi}}\)long. Acceleration rates are often described by the time it takes to reach\({\bf{60}}.{\bf{0}}{\rm{ }}{\bf{mi}}/{\bf{h}}\)from rest. If this time was\({\bf{4}}.{\bf{00}}{\rm{ }}{\bf{s}}\), and Burt accelerated at this rate until he reached his maximum speed, how long did it take Burt to complete the course?

Give an example in which there are clear distinctions among distance traveled, displacement, and magnitude of displacement. Specifically, identify each quantity in your example

a) Take the slope of the curve in Figure 2.64 to find the jogger’s velocity at t = 2.5 s. (b) Repeat at 7.5 s. These values must be consistent with the graph in Figure 2.65.

a) Calculate the height of a cliff if it takes\({\bf{2}}.{\bf{35}}{\rm{ }}{\bf{s}}.\)for a rock to hit the ground when it is thrown straight up from the cliff with an initial velocity of\({\bf{8}}.{\bf{00}}{\rm{ }}{\bf{m}}/{\bf{s}}\). (b) How long would it take to reach the ground if it is thrown straight down with the same speed?

A steel ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.45 m. (a) Calculate its velocity just before it strikes the floor. (b) Calculate its velocity just after it leaves the floor on its way back up. (c) Calculate its acceleration during contact with the floor if that contact lasts 0.0800 ms (\({\bf{8}}{\bf{.00 \times 1}}{{\bf{0}}^{{\bf{ - 5}}}}\;{\bf{s}}\)) . (d) How much did the ball compress during its collision with the floor, assuming the floor is absolutely rigid?
