Chapter 3: Q2CQ (page 119)

Give a specific example of a vector, stating its magnitude, units, and direction.

Short Answer

Expert verified

Force F鈬赌 is a vector quantity with a magnitude of 50 N and directed along the positive x-direction.

Step by step solution

01

Vector

Quantities with both magnitude and direction are called vectors. A vector quantity could be displacement velocity, acceleration, or force.

02

Determine an example

We deal with force, which is a vector quantity, on a daily basis. It is impossible to characterize the force acting on a body without noting its direction. Suppose a block is being pushed by some external force F of magnitude 50 N along the positive x-direction is represented as:

Force acting on a block

Hence, force F鈬赌 is a vector quantity with a magnitude of 50 N and directed along the positive x-direction. Here, N (Newton) is the S.I. unit of force.

A rugby player passes the ball\(7.00{\rm{ m}}\)across the field, where it is caught at the same height as it left his hand.

(a) At what angle was the ball thrown if its initial speed was\(12.0{\rm{ m}}/{\rm{s}}\), assuming that the smaller of the two possible angles was used?

(b) What other angle gives the same range, and why would it not be used?

(c) How long did this pass take?

In 2007, Michael Carter (U.S.) set a world record in the shot put with a throw of 24.77m. What was the initial speed of the shot if he released it at a height of2.10m and 38.0掳threw it at an angle of above the horizontal? (Although the maximum distance for a projectile on level ground is achieved at 45掳 when air resistance is neglected, the actual angle to achieve maximum range is smaller; thus,38掳 will give a longer range than45掳 in the shot put.)

During a lecture demonstration, a professor places two coins on the edge of a table. She then flicks one of the coins horizontally off the table, simultaneously nudging the other over the edge. Describe the subsequent motion of the two coins, in particular discussing whether they hit the floor at the same time.

Suppose you walk \({\bf{18}}.{\bf{0}}\)m straight west and then \({\rm{25}}{\rm{.0}}\) m straight north. How far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position? (If you represent the two legs of the walk as vector displacements A and B , then this problem asks you to find their sum R = A + B .)

Question: Find the components of \({v_{tot}}\) along the \(x\)- and \(y\)-axes in Figure 3.55.

Figure: The two velocities \({{\rm{v}}_{\rm{A}}}\) and \({{\rm{v}}_{\rm{B}}}\) add to give a total \({{\rm{v}}_{{\rm{tot}}}}\).
