4. A sports car accelerates from rest to a final velocity of 64 m/s at a rate of 12.3
Ivanshal [37]

Answer:

t = 5.2\ s

Step-by-step explanation:

Given

a= 12.3m/s^2 --- acceleration

v = 64m/s --- final velocity

u =0m/s --- initial velocity (it is 0, because the car starts from rest)

Required

Determine the time taken

This will be solved using Newton's first equation of motion:

v = u + at

Substitute values for v, u and a

64 = 0 + 12.3*t

64 = 12.3t

12.3t = 64

Make t the subject

t = \frac{64}{12.3}

t = 5.2\ s

<em>Hence, the time taken is approximately 5.2 seconds</em>

Give at least five problems solving about area of a sector of a circle.
Katyanochek1 [597]

See below for the examples of sectors and arcs of a circle

<h3>Area of sector of a circle</h3>

The area of a sector is calculated as:

A = \frac{\theta}{360} * \pi r^2 ---- when the angle is in degrees

A = \frac{\theta}{2} *r^2 ---- when the angle is in radians

Take for instance, we have the following problems involving sector areas

Calculate the area of a sector where the radius of the circle is 7, and

  1. The central angle is 30 degrees
  2. The central angle is π/12 rad
  3. The central angle is 90 degrees
  4. The central angle is π/4 rad
  5. The central angle is 180 degrees

Using the above formulas, the sector areas are:

1. A = \frac{30}{360}* \frac{22}{7} * 7^2 = 12.83

2.  A = \frac{\pi}{12} * 7^2 = 12.83

3. A = \frac{90}{360}* \frac{22}{7} * 7^2 = 38.5

4. A = \frac{\pi}{2} * 7^2 = 38.5

5. A = \frac{180}{360}* \frac{22}{7} * 7^2 = 77

<h3>Examples of arc length</h3>

The length of an arc is calculated as:

L= \frac{\theta}{360} * 2\pi r ---- when the angle is in degrees

L = r\theta ---- when the angle is in radians

Take for instance, we have the following problems involving arc lengths

Calculate the length of an arc where the radius of the circle is 7, and

  1. The central angle is 30 degrees
  2. The central angle is π/12 rad
  3. The central angle is 90 degrees
  4. The central angle is π/4 rad
  5. The central angle is 180 degrees

Using the above formulas, the arc lengths are:

1. L = \frac{30}{360}* 2 * \frac{22}{7} * 7 = 3.7

2.  L = \frac{\pi}{12} * 7 = 3.7

3. L = \frac{90}{360}*2 * \frac{22}{7} * 7 = 11.0

4. L = \frac{\pi}{4} * 7 = 11

5. L = \frac{180}{360}*2 * \frac{22}{7} * 7 = 22

<h3>Examples of the arcs of a circle</h3>

The examples include:

  • A parabolic path
  • Distance in a curve
  • Curved bridges
  • Pizza
  • Bows
