Answer: vf= 364 m/s
Explanation: Use the formula for acceleration:
a= vf - vi / t
Derive for vf:
vf =( at )+ vi
= 5.4 m/s² ( 55s) + 67 m/s
= 364 m/s
Answer:c) Positive acceleration describes an increase in speed; negative acceleration describes a decrease in speed.
Hey
I tried to answer before and it dident let me.
A rainbow. Dispersion is the splitting of radiation into it's different wavelengths.
<em>Angle of Dip is the angle in the vertical plane aligned with magnetic north (the magnetic meridian) between the local magnetic field and the horizontal.</em>
At the same temperature . . .
<em> Fahrenheit reading = (1.8 times Celsius reading) + 32</em> .
F = (1.8 x 232) + 32
F = 417.6 + 32
<em>F = 449.6°</em>
