A plane flies with an average velocity of -98.5 m/s for 45.0s. what was it's displacement?

1 answer:

6 0

V-average velocity
V=98.5 m/s
t-time
t=45s
s-displacement
s=?

V= $\frac{s}{t}$
s=V*t=98.5 $\frac{m}{s}$ *45s=4432.5m=4.4325 km

I think y = 8. Since x = -3 then the equation would be y = -1(-3) +5. -1 times -3 equals 3. So now the equation is y = 3 +5. That would give you 8.

To find the measure of the s angle que are going use the cosine law because we know all the sides of the triangule:

s² = r² + t² - 2*r*t * cos(S)

Then solve the equation

s² -r² - t² = -2*r*t * cos(S)

arccos ((s² -r² - t² /-2*r*t)) = S

arccos (((250)² -(850 cm)²-(940 cm)² /(-2* 850 cm*940 cm) = S

14.9 = S

round to the nearest 10th of a degree

15º = S
