$f=\dfrac{m(v-v_0)}{t}\\
ft=m(v-v_0)\\
ft=mv-mv_0\\
mv=ft+mv_0\\
v=\dfrac{ft+mv_0}{m}$

Challenge A gold mine has two elevators, one for equipment and another for the miners. The

OLEGan [10]

Step-by-step explanation:

The equipment elevator is at a depth of 176 feet (-176 feet), while the miners elevator is at a depth of 210 feet (-210 feet) below the surface

ii. The miners elevator is deeper than that of the equipment.

The speed of an object is the rate at which the object moves.

i.e speed = \frac{distance}{time}

time

distance

Thus,

Speed of the equipment elevator = 4 feet per second

Speed of the miners elevator = 15 feet per second.

Time of descent of the equipment elevator = 30 + 14

= 44 seconds

So that, the distance of the elevator at this time is;

speed = \frac{distance}{time}

time

distance

⇒ distance = speed x time

= 4 x 44

= 176

distance = - 176 feet

The distance of the miners elevator after 14 seconds is:

speed = \frac{distance}{time}

time

distance

⇒ distance = speed x time

= 15 x 14

= 210

distance = - 210 feet

Thus after another 14 seconds, the equipment elevator is at a depth of 176 feet (-176 feet), while the miners elevator is at a depth of 210 feet (-210 feet) below the surface.

Therefore, the miners elevator is deeper than that of the equipment.

If the diagonal of a square is 712, what is its area?

Setler79 [48]

The area of the square whose diagonal 712 units is 253472 units²

Step-by-step explanation:

You can find area of a square by using one of the two rules:

1. Area of a square = s², where s is the length of its side

2. Area of a square = $\frac{d^{2}}{2}$ , where d is the length

of its diagonal

∵ The length of the diagonal of the square is 712 units

∵ The area of the square = $\frac{d^{2}}{2}$

∴ The area of the square = $\frac{712^{2}}{2}$

∴ The area of the square = 253472 units²

The area of the square whose diagonal 712 units is 253472 units²
