A plane flies with an average velocity of -98.5 m/s for 45.0s what was its displacement
svet-max [94.6K]

Answer:

  -4432.5 m . . . or . . . -4.4325 km

Step-by-step explanation:

You can use the formula for average velocity, fill in the given values, and solve for displacement.

  average velocity = displacement/time

  -98.5 m/s = displacement/(45 s)

Multiply by time:

  (-98.5 m/s)(45 s) = displacement = -4432.5 m

_____

Keeping units with the numbers serves as a check on the math. (m/s)·s = m. The units work the same way variables do: they can be multiplied and divided, raised to a power, canceled. If the units of the problem don't work out right, you're probably doing it wrong. (Note, you can only add and subtract numbers that have the same (identical) units--the same rule as for combining like terms.)

Find the distance between the two points K(-7,5), H(5,7)
shutvik [7]

\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ K(\stackrel{x_1}{-7}~,~\stackrel{y_1}{5})\qquad H(\stackrel{x_2}{5}~,~\stackrel{y_2}{7})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ KH=\sqrt{[5-(-7)]^2+[7-5]^2}\implies KH=\sqrt{(5+7)^2+(7-2)^2} \\\\\\ KH=\sqrt{144+4}\implies KH=\sqrt{148}\implies KH\approx 12.17
