wolverine [178]

The total displacement of the hiker's movement is 10 meters, East.

Firstly, displacement is a vector quantity that has both magnitude and direction.

Displacement is an object change in position. In other words it is a change in position of an object . Displacement can also be positive, negative or even zero.

According to the question the hiker walks 15 meters due north then 10 meters east, and finally 15 meters south.

Therefore, the total change in position or total displacement is 10 meters, East.

8090 [49]
<span>Let  Ah be Annie's hour of travel in 1 day and Bh be Brian's hour

to get Brian's hour of travel:
Ah + Bh  = 20

5 (Bh +2 ) + Bh= 20
5 Bh + 10 + Bh=20
6 Bh = 20 - 10
<u>6Bh</u> = <u>10</u>
6          6</span>
Bh =1.66  

To get Ah of travel 1 day
Ah = 5 (Bh + 2)
 <span>    = 5 (1.66 + 2) </span> <span>
     = 5 ( 3.66 )</span>
 Ah = 18.30  

Checking: Ah + Bh =20  <span>

18.30 + 1.66 = 20
</span><span>19.96 = 20</span>  <span>
20 = 20</span>

1. The position of a particle moving along a coordinate axis is given by: s(t) = t^2 - 5t + 1. a) Find the speed of the particle
zimovet [89]

Answer: \left |  2t-5\right |,\ 2,\ 2t-5

Step-by-step explanation:

Given

Position of the particle moving along the coordinate axis is given by

s(t)=t^2-5t+1

Speed of the particle is given by

\Rightarrow v=\dfrac{ds}{dt}\\\\\Rightarrow v=\dfrac{d(t^2-5t+1)}{dt}\\\\\Rightarrow v=\left |  2t-5\right |

Acceleration of the particle is

\Rightarrow a=\dfrac{dv}{dt}\\\\\Rightarrow a=2

velocity can be negative, but speed cannot

\Rightarrow v=\dfrac{ds}{dt}\\\\\Rightarrow v=\dfrac{d(t^2-5t+1)}{dt}\\\\\Rightarrow v=2t-5
