What is the tangent function used to find and what are its units

1 answer:

7 0

The functions of angles are used to find unknown lengths or angles that can't be measured, in terms of known quantities. The trig functions of angles are ratios of lengths, so they're bare naked numbers without units.

Lorico [155]

Answer:

a = 0.701 m / s²

Explanation:

As the game is spinning the acceleration is centripetal

a = v² /r

The park system after a small period of acceleration goes at a constant speed, for which we can use the relations of the uniform motion

v = d / t

the distance of a circle is

d = 2π r

we substitute

a = (2π r / t) ² / r

a = 4 pi² r / t²

let's calculate

a = 4 pi² 12 / 26²

a = 0.701 m / s²

An automobile with 0.500 m radius tires travels 80,000 km before wearing them out. How many revolutions do the tires make, negle

Zinaida [17]

Answer:

n = 25,464,790.89 revolutions

The tires have made 25,464,790.89 revolutions

Explanation:

Given;

Radius of tires r = 0.5 m

Total distance travelled d = 80,000 km = 80,000,000 m

1 revolution = 2πr

Total distance d = number of revolutions n × 2πr

d = n×2πr

d = 2πnr

Making n the subject of formula;

n = d/2πr

Substituting the given values;

n = (80,000,000)/(2×π×0.5)

n = 25,464,790.89470 revolutions

n = 25,464,790.89 revolutions

The tires have made 25,464,790.89 revolutions

Easy defimation of newtons second law of motion

shtirl [24]

Hi pupil here's your answer ::

_______________________________

Newton's Second Law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force.
ie., F=ma

Where F is the force applied, m is the mass of the body, and a, the acceleration produced.

Or in simplest language it is the force applied to a particular object of particular mass multiplied by the acceleration caused by force .
