Chapter 2: Q1PE (page 82)

Find the following for path A in Figure 2.59:

(a) The distance travelled.

(b) The magnitude of the displacement from start to finish.

(c) The displacement from start to finish.

Short Answer

Expert verified
  1. 6 m
  2. 6
  3. +6 m

Step by step solution

01

Distance and displacement

The distance is the total length of the path covered by the body. Its unit is a meter. It is a scalar quantity.

Displacement is the shortest length from the initial and final position.

It is a vector quantity. It is measured by unit m.

If the path is a straight line, only then the distance and displacement will be equal.

02

For particle A, distance and displacement

Path of particle A

  1. The distance traveled by particle A is 6meters.
  2. The magnitude of the displacement, in this case, will be the same as the distance as it is a straight path which is6meters.
  3. The direction of the displacement would be +6m

Conversations with astronauts on the lunar surface were characterized by a kind of echo in which the earthbound person鈥檚 voice was so loud in the astronaut鈥檚 space helmet that it was picked up by the astronaut鈥檚 microphone and transmitted back to Earth. It is reasonable to assume that the echo time equals the time necessary for the radio wave to travel from the Earth to the Moon and back (that is, neglecting any time delays in the electronic equipment). Calculate the distance from Earth to the Moon given that the echo time was 2.56 s and that radio waves travel at the speed of light ( 3 x 108m/s ).

While entering a freeway, a car accelerates from rest at a rate of\({\bf{2}}{\bf{.40}}\;{\bf{m/}}{{\bf{s}}^{\bf{2}}}\)for 12.0 s. (a) Draw a sketch of the situation. (b) List the knowns in this problem. (c) How far does the car travel in those 12.0 s? To solve this part, first identify the unknown, and then discuss how you chose the appropriate equation to solve for it. After choosing the equation, show your steps in solving for the unknown, check your units, and discuss whether the answer is reasonable. (d) What is the car鈥檚 final velocity? Solve for this unknown in the same manner as in part (c), showing all steps explicitly.

Question: A fireworks shell is accelerated from rest to a velocity of\({\bf{65}}.{\bf{0}}{\rm{ m/s}}\)over a distance of\({\bf{0}}.{\bf{250}}\;{\bf{m}}\).

(a) How long did the acceleration last?

(b) Calculate the acceleration.

Give an example (but not one from the text) of a device used to measure time and identify what change in that device indicates a change in time.

How are instantaneous velocity and instantaneous speed related to one another? How do they differ?
