Chapter 2: Q117P (page 39)

From January 26,1977, to September18,1983, George Meegan of Great Britain walked from Ushuaia, at the southern tip of South America, to Prudhoe Bay in Alaska, covering30600km. In meters per second, what was the magnitude of his average velocity during that time period?

Short Answer

Expert verified

The average velocity of George Meegan of Great Britain is 0.15m/s,

Step by step solution

01

Given data

Total distance covered, △x=30600km

02

Understanding the average velocity

Average velocity may be defined as the ratio of net displacement to the total time interval. It is a vector quantity.

The expression for the average velocity is given as follows:

vavg=△x△t ......(1)

Here, △xis the net displacement and △tis total time interval.

03

Determination of the average velocity of George Meegan

The total time period from January 26, 1977 to September 18, 1983 is,

△t=6years,7months,24days=2427days=2427×24×3600s=2.09×108s

Using equation (i), the average velocity is calculated as follows:

vavg=△x△t=30600km×103m1km2.09×108s≈0.15m/s

Thus, the average velocity of George Meegan of Great Britain islocalid="1654751953974" 0.15m/s.

A ball is shot vertically upward from the surface of another planet. A plot of y vs t for the ball is shown in Fig 2-36, where y is the height of the ball above its starting point and t=0 at the instant the ball is shot. The figure’s vertical scaling is set by ys=30.0m.. What are the magnitudes of (a) the free fall acceleration on the planet and (b) the initial velocity of the ball?

A train started from rest and moved with constant acceleration. At one time, it was travelling30 m/s, and 160 mfarther on it was travelling 50 m/s. Calculate (a) the acceleration (b) the time required to travel 160 mmentioned (c) the time required to attain speed of 30 m/s(d) the distance moved from rest to the time the train had a speed of 30 m/s(e) Graph x vs t and v vs t for the train, from rest.

The Zero Gravity Research Facility at the NASA Glenn Research Center includes a 145mdrop tower. This is an evacuated vertical tower through which, among other possibilities, a 1mdiameter sphere containing an experimental package can be dropped. (a) How long is the sphere in free fall? (b) What is its speed just as it reaches a catching device at the bottom of the tower? (c) When caught, the sphere experiences an average deceleration of 25gas its speed is reduced to zero. Through what distance does it travel during the deceleration?

At time t = 0, a rock climber accidentally allows a piton to fall freely from a high point on the rock wall to the valley below him. Then, after a short delay, his climbing partner, who is 10higher on the wall, throws a piton downward. The positions yof the pitons versus tduring the falling are given in Fig. 2-43. With what speed is the second piton thrown?

In an arcade video game, a spot is programmed to move across the screen according tox=9.00t-0.750t3, where x is distance in centimeters measured from the left edge of the screen androle="math" localid="1656154621648" tis time in seconds. When the spot reaches a screen edge, at eitherx=0orx=15.0cm, t is reset to0and the spot starts moving again according tox(t). (a) At what time after starting is the spot instantaneously at rest? (b) At what value of x does this occur? (c) What is the spot’s acceleration (including sign) when this occurs? (d)Is it moving right or left just prior to coming to rest? (e) Just after?(f) At what timet>0does it first reach an edge of the screen?
