The horizontal distance traveled below the table's edge is 29.4 cm.

The given parameters;

The final velocity of the bullet-block system is calculated as follows;

[tex]m_1 u_1 + m_2u_1 = v(m_1 + m_2)\\\\0.015(630) + 4.9(0) = v(0.015 + 4.9)\\\\9.45 = 4.915 v\\\\v = \frac{9.45}{4.915} \\\\v = 1.923 \ m/s[/tex]

The time for the bullet-block system to reach the ground from the table is calculated as follows;

[tex]h = v_0t + \frac{1}{2} gt^2\\\\h = 0 + \frac{1}{2} gt^2\\\\h = \frac{1}{2} gt^2\\\\2h = gt^2\\\\t^2 = \frac{2h}{g} \\\\t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2\times 0.75}{9.8} }\\\\t = 0.153 \ s[/tex]

The horizontal distance traveled below the table's edge is calculated as follows;

[tex]X = vt\\\\X = 1.923 \times 0.153\\\\X = 0.294 \ m\\\\X = 29.4 \ cm[/tex]

Thus, the horizontal distance traveled below the table's edge is 29.4 cm.

Answer:

How do you find the net force?

Explanation:

i think this is want you asked for?

Explanation:

the force exerted from by the car on the wall Is contact force

the force exerted by the wall on the car i don't know

Every action has a comparable or opposite response, as according to Newton's third law. Inferring from this that a car crashing into a wall would apply force to the wall is a logical conclusion. But because the wall remained stationary, the car experiences an equivalent force that eventually causes it to crash.

A force in physics is an input that has the power to change an object's motion. A mass-containing object's velocity can vary, or accelerate, as a result of a force. Intuitively, a push or a pull can also be used to describe forces. Being such a vector quantity, a force does have magnitude and direction. The SI unit metric newton is used to measure it (N). The letter F stands for force.

According to Newton's second law's original formulation, an object's net force is equal to the speed that its momentum is changing over time.

Force is the result of mass times acceleration.

In this case, the acceleration is (v - 0)/t, where t appears to be the amount of time required for automobile A to halt. Newton's third rule of motion states that the car turns the wall with a force, but the wall—which is actually immobile and indestructible—pushes back with a force that is equal to that which was applied to it.

The momentum of the water balloon is equal to: C) 7.2 kgm/s

Given the following data:

To determine the momentum of the water balloon:

In Physics, momentum refers to the multiplication of the mass of an object and its velocity. Thus, momentum is a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

[tex]Momentum = mass \times velocity[/tex]

Substituting the given parameters into the formula, we have;

[tex]Momentum = 0.4 \times 18[/tex]

Momentum = 7.2 kgm/s

Answer:

Samples 2 and 4 are the same liquid

Explanation:

Samples 2 and 4 should be the same liquid because they have the same density as well as the same boiling point. The mass and volumes given do not matter in this case, however they could be used to calculate the density which was already given.

The liquid  present in sample 2 and 4 is same as according to forces of attraction they have same density and boiling points.

Forces of attraction is a force by which atoms in a molecule  combine. it is basically an attractive force in nature.  It can act between an ion  and an atom as well.It varies for different  states  of matter that is solids, liquids and gases.

The forces of attraction are maximum in solids as  the molecules present in solid are tightly held while it is minimum in gases  as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

The physical properties such as melting point, boiling point, density  are all dependent on forces of attraction which exists in the substances.

Explanation:

The energy is not  conserved because:

1. Energy may still be leaving the system through friction.

2. There could be measurement error that account for the missing energy

Given that a different group roll a round  object down a ramp instead of dropping it. They measure the initial  height to calculate gravitational potential energy, use the motion  detector to track the final velocity, and calculate the kinetic energy of  the object at the end.

Despite all their careful measurements, it appears that energy is not

conserved because

1. Energy may still be leaving the system through friction. In which the energy lost will be converted to thermal energy

2. There could be measurement error that account for the missing energy. The may occur due to systematic error or parallax error

The object is not moving as fast at the bottom as the initial gravitational potential would have led them to predict. This is not as a result of rotational energy. There is nothing like rotational energy.

Answer:

6400km is the closest

Explanation:

16 n/c to the northwest lies an electric field. hence it qualifies as a direction. Thus, the correct response is (b). It is assumed that the field's direction corresponds to the direction in which a positive test charge should experience force.

With a positive point charge, the electric field radiates outward, whereas with a point charge that's negative, it radiates in.

How big and which way is the electric field pointing?

A positive point charge is pointed directly away by the electric field, while a negative point charge is pointed directly inside the opposite direction. When you go away again from point charge, the power of the electrical field diminishes as 1 / r 2 1/r21, slash, r, square.
