I don't even know can anybody help this person
Whan object is at equilibrium, then the forces are balanced. Balanced is the key word that is used to describe equilibrium situations.
kinetic energy to gravitational potential energy
When we say directly northeast that is equivalent
to 45˚ north of east.
First let us determine the north and east
components of the acceleration using cos and sin functions:<span>
North = 2.18 * sin 45
East = 2.18 * cos 45
<span>Then we set to determine the east component of the plane’s
displacement by calculating using the formula:
d = vi * t + ½ * a * t^2
d = 135 * 18 + ½ * 2.18 * cos 45 * 18^2
<span>d = 2430 + 353.16 * cos 45 = 2679.72 m</span>
Calculating for the north component:
North = ½ * 2.18 * sin 45 * 18^2 </span></span>
North = 249.72 m
Hence magnitude is:
Magnitude = sqrt (2679.72^2 + 249.72^2)
Magnitude = 2,691. 33 m<span>
</span>
Calculating for angle:
Tan θ = North ÷ East <span>
<span>Tan θ = 249.72 m ÷ 2679.72 m</span></span>
θ = 5.32°<span>
</span>
So the plane was flying at 2,691. 33 m at 5.32<span>°</span>
