When the pivot point of a balance is not at the center of mass of the balance, how is the net torque on the balance calculated

Physics
1 answer:
Mashcka [7]3 years ago
6 0

Answer:

It is calculated as Force × perpendicular distance.

Explanation:

Torque is a rotational force and twisting force that can cause an object to rotate in it's axis. This cause angular rotation.

The torque due to gravity on a body about its centre of mass is zero because the centre of mass is the that point of the body at which the force acts by the gravity that is mg.

But if the pivot point of a balance is not at the centre of mass of the balance, it will be FORCE × PERPENDICULAR DISTANCE because at that point, there is no centre in which the force act on a body by gravity. The distance and force will be use to calculate.

A particle is moving along a projectile path where the initial height is 160 feet with an initial speed of 144 feet per second.
Leviafan [203]
Assuming Earth's gravity, the formula for the flight of the particle is: 

<span>s(t) = -16t^2 + vt + s = -16t^2 + 144t + 160. </span>

<span>This has a maximum when t = -b/(2a) = -144/[2(-16)] = -144/(-32) = 9/2. </span>

<span>Therefore, the maximum height is s(9/2) = -16(9/2)^2 + 144(9/2) + 160 = 484 feet. </span>

Find the final velocity of a 40 kg skateboarder traveling at an initial velocity of 10 m/s that moves up a hill from a height of
slavikrds [6]

Answer:

vf = 0

Explanation:

Since the initial height hi = 0, we can rewrite the energy equation as

vf^2 = vi^2 - 2ghf = (10 m/s)^2 - 2(10 m/s^2)(5 m) = 0

Therefore, his final velocity vf is

vf = 0

An airplane flies with a constant speed of 840km/h. how far can it travel in 1 hour?
arlik [135]
Distance = speed X time

In this example, the speed of the airplane = 840km. The time (that the question is asking)is how far can it travel in 1 hour.

So just plug in your numbers.

Distance = 840km X 1 hour = 840km/hour or 840km for short.

How fast is a ball going when it hits the ground after being dropped from a
Umnica [9.8K]

Answer:

Option D.

Explanation:

Data:

  • Height (h) = 9 m
  • Gravity (g) = 9.8 m/s²
  • Velocity Final (Vf) = ?

Use formula:

  • Vf² = 2 * g * h

Replace:

  • Vf² = 2 * 9.8 m/s² * 9 m

Multiply gravity with height:

  • Vf² = 2 * 88.2

Multiply:

  • Vf² = 176.4

Solve the square root:

  • Vf = 13.3

How fast is the ball going?

The speed is going at a speed of <u>13.3 meters per second.</u>
