Chapter 2: Q10PE (page 82)

Tidal friction is slowing the rotation of the Earth. As a result, the orbit of the Moon is increasing in radius at a rate of approximately4鈥塩尘/测别补谤. Assuming this to be a constant rate, how many years will pass before the radius of the Moon鈥檚 orbit increases by3.84脳106鈥�m(1%) ?

Short Answer

Expert verified

9.6脳107鈥墆

Step by step solution

01

Given Data

  • Speed=4鈥塩尘/测=0.04鈥尘/测
  • Total radius = 3.84脳106鈥�m
02

Time is taken to increase the 1% radius of the moon

Speed can be calculated as the distance that is traveled by an object in a time period.

Speed鈥�=DistanceTime

It is a scalar quantity.

The time taken can be calculated as:

Time=DistanceSpeed

Substituting the values in the above expression, we get:

T=3.84脳106鈥尘0.04鈥尘/测=96,000,000鈥�y

Hence,9.6脳107鈥墆 is needed to increase the radius of the moon by 1%.

(a) What was her average speed?

(b) If the straight-line distance from her home to the university is10.3km in a direction25.0潞 south of east, what was her average velocity?

(c) If she returned home by the same path7h30min after she left, what were her average speed and velocity for the entire trip?

What is the last thing you should do when solving a problem? Explain.

(a) Sketch a graph of acceleration versus time corresponding to the graph of velocity versus time given in Figure 2.57.

(b) Identify the time or times ( ta, tb, tc , etc.) at which the acceleration is greatest.

(c) At which times is it zero?

(d) At which times is it negative?

Is it possible for velocity to be constant while acceleration is not zero? Explain.
