The correct answer is

In fact, the displacement is a vectorial quantity that corresponds to the difference between the initial and the final position of an object in motion. In this problem, the final position of the ball is equal to its initial position (because the ball returns back to where it was launched), so the displacement of the ball is zero.

A number line goes from negative 5 to positive 5. Point D is at negative 4 and point E is at positive 5. A line is drawn from po

saul85 [17]

The location of the point F that partitions a line segment from D to E ( $\overline{DE}$ ), that goes from <u>negative 4</u> to <u>positive 5,</u> into a 5:6 ratio is fifteen halves (option 4).

We need to calculate the segment of the line DE to find the location of point F.

Since point D is located at <u>negative -4</u> and point E is at <u>positive 5</u>, we have:

$\overline{DE} = E - D = 5 - (-4) = 9$

Hence, the segment of the line DE ( $\overline{DE}$ ) is 9.

Knowing that point F partitions the line segment from D to E ( $\overline{DE}$ ) into a <u>5:6 ratio</u>, its location would be:

$F = \frac{5}{6}\overline{DE} = \frac{5}{6}9 = 5*\frac{3}{2} = \frac{15}{2}$

Therefore, the location of point F is fifteen halves (option 4).

Find the y-component of this vector:73.3,12.0m. Remember, angles are measured from the +x axis.

Rainbow [258]

Answer:

11.5 meters

Explanation:

73.3°, 12.0m

The y-component is the magnitude of the vector times the sine of the angle measured from the +x axis.

y = 12.0 sin (73.3°)

y = 11.5

The y-component is 11.5 meters.

Football player 1 has a mass of 80 kg and a velocity of 2 m/s east while player 2 has a mass of 70 kg and a velocity of 3 m/s we

sukhopar [10]

The total momentum of the system is equal to 50 Kgm/s.

<u>Given the following data:</u>

Mass 1 = 80 kg

Velocity 1 = 2 m/s east.

Mass 2 = 70 kg

Velocity 2 = 3 m/s west.

To determine the total momentum of the system:

Mathematically, momentum is given by the formula;

$Momentum = mass \times velocity$

<u>For Football player 1:</u>

$Momentum = 80 \times 2$

Momentum 1 = 160 Kgm/s.

<u>For Football player 2:</u>

$Momentum = 70 \times 3$

Momentum 1 = 210 Kgm/s.

Now, we can calculate the total momentum of the system:

$Total\;momentum = momentum \;2 - momentum \;1\\\\Total\;momentum = 210-160$

Total momentum = 50 Kgm/s.

<u>Note:</u> We subtracted because the football players were moving in opposite directions.
