If your weight is 132 pounds, how much work is done if you climb a flight of stairs 12 meters high?

Mathematics

Temka [501]3 years ago
6 0

Answer:

7040.76 Joule

Step-by-step explanation:

In order to make yourself be able to climb upstairs, you need to work against the force of gravity. The force with which you pull yourself up is equal to the force of gravity exerted on you by the gravitational force.

So here, the net force involved is Mass(in Kg) multiplied by Acceleration due to gravity.

132 pounds = 59.8742 Kg

Net force = 59.87 × 9.8 = 586.73

As we know, the workdone is calculated by Multiplying the Net force with the Net displacement. Here, in this case the net displacement is 12 meters.

So,

Workdone = 586.73 × 12 = 7040.76 Joule

Find the length of the missing side. 34 ft ? 30 ft​
mart [117]

Step-by-step explanation:

let p be perpendicular, ( ^ refers to exponent )

by pythagorus theorem,

hypotenuse^2 = perpendicular^2 + base^2

  • 34^2 = p^2 + 30^2
  • 1156 = p^2 + 900
  • p^2 = 1156 - 900
  • p^2 = 256
  • p = root 256
  • p = 16

so we get p = perpendicular = 16 feets

3. A prop for the theater club's play is constructed as a cone topped with a half-sphere. What is the volume of the prop? Round
Maksim231197 [3]

Answer:

8138.88 cubic unit.

Step-by-step explanation:

Given that,

Radius, r = 12

Height, h = 18

We need to find the volume of the prop. The volume of a cylinder is given by the formula as follows :

V=\pi r^2 h\\\\V=3.14\times 12^2 \times 18\\\\V=8138.88\

So, the volume of the cylinder is 8138.88 cubic unit.

On the graph of the equation 8x − 3y = 24, what is the value of the y-intercept
Virty [35]
The y-intercept is -8 because when you put it in standard form you subtract 8x from both sides which give you-3y=-8x+24. Then you divide both sides by -3 which gives you y=8/3x-8. Since the form is y=mx+b, b is the y-intercept so it would be -8.
