What is the kinetic energy of a 1.4 kg discus with a speed of 22.5 m/s?

Answers

Answer 1

Answer:

354.375 J

Step-by-step explanation:

The formula to find kinetic energy is:

[tex]\frac{1}{2}[/tex] × mass × [tex](Speed)^{2}[/tex]

Mass = 1.4 kg

Speed = 22.5m/s

So the kinetic energy will be:

[tex]\frac{1}{2}[/tex] × 1.4 × [tex]22.5^{2}[/tex]

= [tex]\frac{1}{2}[/tex] × 1.4 × 506.25

Kinetic energy= 354.375 joules

Answer 2
The answer would be 345 J

What is a good estimate for this angle measurement?

A. 15 degrees
B. 30 degrees
C. 45 degrees
D. 60 degrees

Answers

Answer:

B. 30°

It looks like that

Answer: B. 30 degrees

Step-by-step explanation:a acute angle is 45° closest to 45° is 30°

The sum of the measures of the angles of all triangles is 180 degrees. If one angle of the triangle measures 45 degrees, and the other two angles are equal, what is the measure of each of the other two angles? Choose the equation that represents the situation. Let "a" represent the unknown angle measurement.

A. 2 + a + 45 = 180
B. 2a + 45 = 180
C. 45a + 2 = 180

Answers

Answer:

B

Step-by-step explanation:

2a+45=180

subtract 45 from both sides which equals 2a=135

divide both sides by 2 which would solve for a.

Answer:

∠ABC= 40°  ∠CBD=60°  ∠EBD=80°

Step-by-step explanation:

Step 1: 2x+3x+4x=180

          A straight line is 180 degree's, and to get the value of the different angles, you have to add the three angle measures.

Step 2: 9x=180

Find the surface area of the triangular prism.

Answers

Answer:

Triangular prism 1:    132

Triangular prism 2:   828

Step-by-step explanation:

1) triangle+triangle+rectangle+rectangle+rectangle

A of triangle=3*4 divided by 2

12/2= 6

since there are 2 triangles we do 6*2= 12

A of rectangle 1= 10*5= 50

A of rectangle 2= 10*4= 40

A of rectangle 3= 10*3= 30

so SA of whole figure is 12+50+40+30= 132

2) triangle+triangle+rectangle+rectangle+rectangle

A of triangle=9*12 divided by 2

108/2=54

since there are 2 triangles we do 54*2=108

A of rectangle 1= 9*20=180

A of rectangle 2= 15*20=300

A of rectangle 3= 12*20= 240

so SA of whole figure is 108+180+300+240=828

Suppose each dimension of a cube is increased. What happens to the surface area when each dimension is doubled, tripled or, quadrupled?

Answers

Answer:

Step-by-step explanation:

Surface area of a cube = 6a²

When each dimension is doubled,  Side =2a

Surface area = 6*(2a)² = 6 * 4*a² = 4*(6a²)

So, when each dimension is doubled, surface area is 4 times of the original surface.

a = 3a

Surface area = 6*(3a)² = 6 * 9 *a² = 9 *6a²

                     = 9 times the original area

a = 4a

Surface area = 6*(4a)² = 6* 16 * a²

                     = 16 * (6a²)

                     = 16 times of original area
