A roller coaster accelerated from rest to 55 m/s by the time it reached the first hill. The roller coaster took 15 seconds to cl

GalinKa [24]

Answer:

I believe the acceleration is 3.66666666667 m/s

Step-by-step explanation:

Acceleration formula: a = vf - vi / t

Initial velocity: 0 (I believe it was 0, as it wasn't moving in the beginning)

Final velocity: 55 m/s

Time: 15 s

Substituting values: 3.66666666667 = 55 - 0 / 15

Find AB. Round to the nearest tenth. 61°

anzhelika [568]

Answer:

AB ≈ 14.3

Step-by-step explanation:

We're given two sides (BC and CA) and an angle (C) between them; the law of cosines is a good tool for calculating the third side of the triangle here. To remind you, the law of cosines tells us the relationship between the sides of a triangle with side lengths a, b, and c:

$c^2=a^2+b^2-2ab\cos{C}$

Where C is the angle between sides a and b. c is typically the side we're trying to find, so on our triangle, we have

$c=AB\\a=BC=16\\b=CA=5\\C=m\angle C=61^{\circ}$

Substituting these values into the law of cosines:

$c^2=16^2+5^2-2(16)(5)\cos{61^{\circ}}\\c^2=256+25-160\cos{61^{\circ}}\\c^2=281-160\cos{61^{\circ}}\\c=\sqrt{281-160\cos{61^{\circ}}}\\c\approx 14.3$
