Chapter 1: Q. 30 (page 30)

Estimate (don鈥檛 measure!) the length of a typical car. Give your answer in both feet and meters. Briefly describe how you arrived at this estimate

Short Answer

Expert verified

The length of a car is4.5 meters or 13.5 feets

Step by step solution

01

Write the measurement unit of distance.

  • The quantity like the length, height, or distance is measured in the meters.
  • Meter is the SI unit of distance.
  • The units such as inch, feet, and mile are also used to measure the distance.
02

To estimate the length of a typical car

1 meter = 3 feet (approximately)

  • On average, the length of a car is4.5 meters
  • It can also be expressed in terms of feet
    Since, 1 m = 3 ft, thus;
    4.5 m = 4.5 (3 ft) = 13.5ft
    Therefore, the length of the car is 13.5 feet

FIGURE EX1.18 shows the motion diagram of a drag racer. The camera took one frame every 2 s.

a. Measure the x-value of the racer at each dot. List your data in a table similar to Table 1.1, showing each position and the time at which it occurred.

b. Make a position-versus-time graph for the drag racer. Because you have data only at certain instants, your graph should consist of dots that are not connected.

Does the object represented in FIGURE Q1.4 have

a positive or negative value of ax? Explain.

You are watching a jet ski race. A racer speeds up from rest

to 70 mph in just a few seconds, then continues at a constant

speed. Draw a basic motion diagram of the jet ski, using images

from the video, from 10 s before reaching top speed until 10 s

afterward.

Problems 50 show a partial motion diagram. For each:

a. Complete the motion diagram by adding acceleration vectors.

b. Write a physics problem for which this is the correct motion

diagram. Be imaginative! Don鈥檛 forget to include enough

information to make the problem complete and to state clearly

what is to be found.

c. Draw a pictorial representation for your problem.

A rocket is launched straight up. Draw a basic motion diagram,

using the images from the video, from the moment of liftoff until

the rocket is at an altitude of 500 m.
