A person travels 1.5 km in 6 minutes, how fast were they traveling in meters per second?

Evgen [1.6K]

Answer:

4.167m/sec

Explanation:

1km=1000m

1.5km=1500m

1min=60sec

6min=360sec

In 360sec they travel 1500m

In 1 sec they travel=1500m/360

1sec=4.167m

You have two vectors, which are 2.59 m at 30.0° north of east and 4.18 m at 60.0° north of west. What is the magnitude in meters

Answer: $\ec{r}=0.153\hat{i}+4.914\hat{j}$ v

Explanation:

Given

Vector 1

$\vec{a}=2.59\left ( cos30\hat{i}+sin30\hat{j}\right )$

Vector 2

$\vec{b}=4.18\left ( -cos60\hat{i}+sin60\hat{j}\right )$

Resultant $\vec{r}=\vec{a}+\vec{b}$

$\vec{r}=2.59\left ( cos30\hat{i}+sin30\hat{j}\right )+4.18\left ( -cos60\hat{i}+sin60\hat{j}\right )$

$\vec{r}=0.153\hat{i}+4.914\hat{j}$

$|r|=4.916$
