Determine the kinetic energy of a 1000-kg roller coaster car that is moving with a speed of 20.0m/s.

elixir [45]

In this question all required information's are already provided. Based on these details the answer to the question can be easily determined. Let us now write down all the information's that are already given.
Mass of the roller coaster = 1000 kg
Velocity of the roller coaster = 20.0 m/s
We know the formula for finding the kinetic energy is
Kinetic energy = 0.5 * mass * (velocity) ^2
   = 0.5 * 1000 * (20)^2
   = 0.5 * 1000 * 400
   = 200000 Joules
So the Kinetic energy of the roller coaster is 200000 joules.

Work out the lengths of sides a and b. Give your answers to 1 decimal place.

Tju [1.3M]

Answer:

$A = \sqrt{89}$

$B = \sqrt{145}$

Step-by-step explanation:

$1)\ 8^2 + 5^2 = A^2$

$2)\ A^2 = 64 + 25$

$3)\ A^2 = 89$

$4)\ A = \sqrt{89}$

$1)\ B^2 + 12^2 = 17^2$

$2)\ B^2 + 144 = 289$

$3)\ B^2 = 145$

$B = \sqrt{145}$

Answer:

The equation of the boundary of the region is (x+2)² + (y-1)² = 25

Step-by-step explanation:

The satellite is positioned at (-2,1) and can sense the presence within 5 miles of its position.

The boundary of the region is a circle with center (-2,1) and radius 5.

The equation of the circle with center (h,k) and radius r is given by

(x-h)²+(y-k)²=r²

The equation of the circle with center (-2,1) and radius 5 is given by

(x+2)²+(y-1)²=5²=25

(x+2)² + (y-1)² = 25 is the required equation of the boundary of the region.

hat is the area of a sector with a central angle of 4π5 radians and a radius of 11 cm? Use 3.14 for π and round your final answe

dusya [7]

4/5 PI radians = 144 degrees
sector area = central angle / 360 * PI * radius^2
sector area = 144 / 360 * PI * 11^2
sector area = 152.0530844337 square centimeters
sector area = 152.05 square centimeters
