Four uniform spheres, with masses mA = 200 kg, mB = 250 kg, mC = 1700 kg, and mD = 100 kg, have (x, y) coordinates of (0, 50 cm)

rusak2 [61]

Answer:

$F_2=2.43\times10^{-19}\ N$

$\theta=21.496^{\circ}$ in the anticlockwise direction from the positive x- axis.

Explanation:

Given are the masses of various spheres with their names in subscript:

$m_A=200\ kg$

$m_B=250\ kg$

$m_C=1700\ kg$

$m_D=100\ kg$

Now their respective coordinate positions (in cm) are as given below:

$P_A=(0,50)$

$P_B=(0,0)$

$P_C=(-80,0)$

$P_D=(40,0)$

Now force on B due to A:

$F_{BA}=G\times \frac{200\times 250}{50^2}$

$F_{BA}=20G\ N$

Now force on B due to C:

$F_{BC}=G\times \frac{1700\times 250}{80^2}$

$F_{BC}=66.406G\ N$

Now force on B due to D:

$F_{BD}=G\times \frac{100\times 250}{40^2}$

$F_{BD}=15.625G\ N$

We observe that the forces due to masses C&D act opposite in direction.

So, the net force in the x-direction:

$F_x=F_{BC}-F_{BD}$

$F_x=66.406G-15.625G$

$F_x=50.781G\ N$ in the positive x-direction

We have only one force in y-direction due to mass A.

So,

$F_y=20G\ N$ in the positive y-direction.

Now the net force:

$F_2=\sqrt{F_y^2+F_x^2}$

$F_2=\sqrt{(20G)^2+(50.781G)^2}$

$F_2=54.5776G^2\ N$

$F_2=2.43\times10^{-19}\ N$

Now the direction of this force with respect to x-axis:

$tan\ \theta=\frac{F_y}{F_x}$

$tan\ \theta=\frac{20G}{50.781G}$

$\theta=21.496^{\circ}$ in the anticlockwise direction from the positive x- axis.

If you are in motion can you have the same speed as someone else in motion but different velocities? Give an example

geniusboy [140]

Answer:

Yes

Explanation:

Velocity is a vector quantity, meaning it has size and direction, as opposed to speed, a scalar quantity which only has size.

An example is speed may be 30km/h, and an example of velocity is 30km/h East.

Therefore two people can have the same speed and different velocities because they can be traveling in different directions.

For example, you and your friend could be doing shuttles together but you started at one wall and they started at the other, so even though you are running at the same speed, you always have different velocities because they are running in the opposite direction as you.

Hope this helped!

100 POINTS + BRAINLIEST, HEART, & FIVE STAR.

saveliy_v [14]

Answer:

Question 1 the answer is 5 cm for the one pulley system, I just took the quiz

Question 2 is 10 cm

Explanation:

The rope only needs to move 5 cm for the mass to move from 15 to 20.

For the 2 pulley system the string has to move twice as far making it 10 cm. I took the quiz and got 100%
