force acting on the object is​

Answer 1

The net force acting on the object is 0 newton.

Given:

An object of mass 200 g is sliding down on a rough inclined plane with a constant speed of 12 m/s.

To Find:

The net force acting on the object.

Solution:

To Find the net force acting on the object we will follow the following steps:

As we know,

Force is a vector quantity that can bring about a change in the direction and motion of an object when applied. The unit of force is kgms-² and Newton(N).

Because F = ma

Here, m is the mass and a is the acceleration.

Unit if the mass is kg and the unit of acceleration is

$m {s}^{ - 2}$

So, the unit of force is

$mass \times acceleration = kg \times \: m {s}^{ - 2} = kgm {s}^{ - 2}$

Now,

As the object is moving with a constant velocity it means its acceleration is 0 because acceleration is the change in velocity per unit of time.

According to the question, mass = 200g = 0.2Kg

Velocity = 12 m/s

Acceleration = 0 ms-²

Force = mass × acceleration = 0.2 × 0 =$0 \: newton$

Henceforth, the net force acting on the object is 0 newton.

Answer 2

The net forcing acting on the object is 0 newton.

GIVEN: A 200 g item is descending at a steady speed of 12 m/s on a crooked inclined plane.

TO FIND: The total force exerted on the target.

SOLUTION:

We will take the following actions to determine the net force operating on the object:

The fact is,

When applied, force, a vector quantity, can cause an item to change its direction and motion. Force is measured in kgms⁻² and Newton (N).

When F = ma

In this case, the mass is m, and the acceleration is a.

If the mass is in kilograms and the acceleration is ms⁻² in units.

Consequently, the unit of force is now.

Consequently, the unit of force is now.

Mass × Acceleration = kg × MS ⁻²

Since acceleration is the change in velocity per unit of time, the fact that the object is moving at a constant speed means that its acceleration is zero.

In response to the inquiry, mass = 200g = 0.2Kg

The speed is 12 m/s.

Acceleration equals 0 ms-2.

Force = mass × acceleration × (0.2 × 0)

       = 0 newton

The object is now subject to a net force of zero newtons.
