Answer:

<em>Fn = 50 N</em>

Explanation:

<u>Net Force</u>

The net force is the sum of all the forces acting on an object.

When all the forces act in a single line, the direction of the forces is given by their signs. Positive signs are assumed to be up and left on both axes.

The box being raised by a force has a weight of W=-125 N. The negative sign indicates the weight points down. The accelerating force goes up and its value is F=175 N. The positive sign indicates this force pushes the box up.

The forces acting on the box are:

The weight W=-125 N

The accelerating force F=175 N

The net force is

Fn = W + F = -125N + 175 N

Fn = 50 N

The jet fuel in an airplane has a mass of 97.5 kg and a density of 0.804 g/cm3. What is the volume of this jet fuel
Mnenie [13.5K]

The volume of the jet fuel is 1.213 x 10⁵ cm³.

<h3>What is density?</h3>

Density is a physical property that measures the ratio of mass to volume occupied by an object.

Density = mass/volume

Volume = mass/density

<h3> Volume of the jet fuel</h3>

The volume of the jet fuel is calculated as follows;

Volume = (97500 g)/(0.804 g/cm³)

Volume = 1.213 x 10⁵ cm³

Thus, the volume of the jet fuel is 1.213 x 10⁵ cm³.

In a police ballistics test, 2.00-g bullet traveling at 700 m/s suddenly hits and becomes embedded in a stationary 5.00-kg wood
Ratling [72]

Answer:

The bullet will lose momentum

Explanation:

mass of the bullet, m₁ = 2.0 g = 0.002 kg

initial velocity of the bullet, u₁ = 700 m/s

mass of the wood block, m₂ = 5 kg

initial velocity of the wood block, u₂ = 0

let the final velocity of the bullet-block system after collision = v

Apply the principle of conservation of linear momentum;

m₁u₁ + m₂u₂ = v(m₁ + m₂)

(0.002 x 700) + (5 x 0) = v(0.002 + 5)

1.4 = 5.002 v

v = 1.4 / 5.002

v = 0.28 m/s

Change in momentum of the bullet is given by;

ΔP = m₁v - m₁u₁

ΔP = m₁(v - u₁)

ΔP = 0.002( 0.28 - 700)

ΔP = -1.4 kg.m/s

Therefore, the bullet will lose momentum
