Explanation:

Such problems, including homelessness, teen parenting, substance abuse,, complicate students' efforts to learn. Other social problems, such as vandalism, school violence, and the dropout rate, are exacerbated when students feel alienated from the school structure.

Explain how it is that many Americans find themselves swimming in credit card debt, unable to pay down their

Misha Larkins [42]

Answer:

People use their card for a purchase they can’t afford or want to defer payment, and then they make only the minimum payment that month. Soon, they are in the habit of using their card to purchase things beyond their budget. Since they are making only the minimum monthly payment, it won’t seem to matter much if their credit card balance gets a bit larger. This is a quick illustration to show how their “small balance” of just a few thousand dollars can really mean paying more than double that amount over the years because of interest. Also, when they are trapped in this mindset, their balance barely budges. With a debt of $5,000 and a minimum monthly payment of $150 (at 3% of the total balance), they will only be paying $47.30 each month toward their principal. The rest goes toward their interest accrued.

a 15.0 kg block is attached to a very light horizontal spring of force constant 575 n/m and is resting on a smooth horizontal ta

Luden [163]

The instantaneous velocity of the 15 kg. mass just after collision can be found by the principle of linear momentum.

a) The speed of the 15 kg. just after collision is 2 m/s.

b) The type of collision is inelastic collision

c) The compression of the spring is approximately 0.323 m.

Reasons:

The given parameters are;

Mass of the block attached to the spring, m₁ = 15.0 kg

Force constant of the spring, K = 575 N/m

Mass of the stone that strikes the block, m₂ = 3.00 kg

Speed of the stone, v₂ = 8.00 m/s

Speed with which the stone rebounds, v₃ = 2.00 m/s

a) The total initial momentum = 3 kg. × 8 m/s = 24 kg·m/s

The final momentum, just after collision = 3 × (-2) kg·m/s + 15 kg ×v₁

By conservation of momentum, we have;

24 kg·m/s = 3 × (-2) kg·m/s + 15 kg ×v₁

$v_1 = \dfrac{24 \, kg \cdot m/s + 6 \, kg \cdot m/s}{15 \, kg} = 2 \, m/s$

The speed of the 15 kg. just after collision, v₁ = 2 m/s.

b) A collision is elastic when the kinetic energy of the collision is conserved

The initial kinetic energy, K.E.₁ = 0.5 × 3 kg. ×(8 m/s)² = 96 J

The sum of the final kinetic energy are;

0.5 × 3 kg. × (2 m/s)² + 0.5 × 15 kg × (2 m/s)² = 36 J

The initial kinetic energy ≠ The final kinetic energy

Therefore, the collision is not elastic

Kinetic energy of the block, K.E. = 0.5 × 15 kg × (2 m/s)² = 30 J

Elastic energy gained by the block = 0.5 × K × x² = 0.5 × 575 N/m × x²

Therefore;

0.5 × 575 N/m × x² = 30 J

$x^2 = \dfrac{30 \, J}{0.5 \times 575 \, N/m} = \dfrac{12}{115} \, m^2$

$x = 2 \cdot \sqrt{\dfrac{3}{115} } \approx 0.323$

The compression of the spring, x ≈ 0.323 m.

It’s takes 5100 Nof force to accelerate a Ford Mustang 3 m/s2 what is the mass of the car

xxMikexx [17]

The force is 5100 N which is accelerating a Ford Mustang. The mass of the car is 1700 kg.

<h3>What is force?</h3>

A force is an influence that can alter an object's motion. A force can modify the velocity of a mass item. Force is calculated in Newton.

In physics, mass is a quantitative measure of inertia, which is a fundamental property of all matter. Mass is measured in kilograms and grams.

The force is given as 5100 N

The acceleration is 3 m/s

The mass is to be calculated

F = ma

m = F / a

m = 5100 / 3

m = 1700 kg

Therefore, the mass of the car is 1700 kg.
