Chapter 2: Q115P (page 39)

In 1889, at Jubbulpore, India, a tug-of-war was finally won after role="math" localid="1654754892705" 2h41min, with the winning team displacing the center of the rope 3.7m. In centimeters per minute, what was the magnitude of the average velocity of that center point during the contest?

Short Answer

Expert verified

The magnitude of the average velocity of the center point of rope during the contest is2.3cm/min

Step by step solution

01

Given data

Displacement, Δx=3.7m

Time period, Δt=2h41min

02

Understanding the average velocity

Converts the displacement into centimeters.

Δx=3.7×100cm=370cm

Converts the time interval into minutes.

Δt=(2×60)min+41min=120min+41min=161min

Using equation (i), the magnitude of average velocity of center point is calculated as follows:

vavg=ΔxΔt=370cm161min≈2.30min/cm

Thus, the average velocity of the center point by considering the displacement over the total time is2.30min/cm

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?

Figure shows a general situation in which a stream of people attempts to escape through an exit door that turns out to be locked. The people move toward the door at speed Vs=3.5m/s, are each d=0.25 m in depth, and are separated by L=1.75 m. The arrangement in figure 2-24 occurs at time t=0. (a) At what average rate does the layer of people at door increase? (b) At what time does the layer’s depth reach 5 m? (The answers reveal how quickly such a situation becomes dangerous)

When startled, an armadillo will leap upward. Suppose it rises0.544 min first0.200 s, (a) what is its initial speed as it leaves the ground? (b)What is its speed at a height of0.544 m? (c) How much higher does it go?

The wings on a stonefly do not flap, and thus the insect cannot fly. However, when the insect is on a water surface, it can sail across the surface by lifting its wings into a breeze. Suppose that you time stoneflies as they move at constant speed along a straight path of a certain length. On average, the trips each take7.1swith the wings set as sails and 25.0swith the wings tucked in. (a) What is the ratio of the sailing speed vsto the non-sailing speed localid="1654754209433" vns? (b) In terms oflocalid="1654754226410" vs, what is the difference in the times the insects take to travel the first2.0malong the path with and without sailing?

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.
