An object of mass 0.50 kg is released from the top of a building of height 8 m. The object experiences a horizontal constant for

liberstina [14]

To solve this problem with the given elements we will apply the linear motion kinematic equations. We will start by calculating the time taken, with the vertical displacement data. Subsequently, with the components of the acceleration, we will obtain the magnitude of the total acceleration, to finally obtain the horizontal displacement with the data already found.

PART A) From vertical movement we know that the acceleration is equivalent to gravity and the displacement is 8m so the time taken to carry out the route would be

$h = \frac{1}{2} gt^2$

Here,

$h = 8 m$

$g = 9.8 m/s^2$

Replacing,

$8 = 0.5 * 9.8 * t^2$

$t = 1.277 sec$

PART B) Now, Magnitude of acceleration

$a = \sqrt{a_x^2 + a_y^2}$

$a_x = \frac{1.9}{0.5} = 3.8 m/s^2$

$a_y = g = 9.8 m/s^2$

Thus, magnitude of net acceleration

$a = \sqrt{3.82^2 + 9.8^2}= 10.51 m/s^2$

PART C) Finally the displacement along horizontal direction is:

$s =v_0 t + \frac{1}{2} a t^2$

$s = 0 + \frac{1}{2} (3.8)(1.277)^2$

$s = 3.098 m$

Therefore the distance traveled along the horizontal direction before it hits the ground is 3.098m

Two blocks are initially at rest with a compressed spring between them. When the spring is released, the 2m block moves to the l

Vlad1618 [11]

<u>Answer:</u>

In an <u>inelastic collision</u> the kinetic energy is not conserved, but <u>the total momentum of the system is conserved</u>.

In other words; the Initial momentum $P_{i}$ is equal to the Final Momentum $P_{f}$ :

$P_{i}=P_{f}$

Then:

This means that after the collision the kinetic energy is transformed (dissipated) into another type of energy (caloric energy, for example); and there may be deformation in the blocks.

Therefore, the sentence that best describes this situation is:

<h2>The total momentum is zero. </h2>

An automobile accelerates from zero to 30 m/s in 6.0 s. The wheels have a diameter of 0.40 m. What is the average angular accele

leva [86]

To solve this problem we will use the concepts related to angular motion equations. Therefore we will have that the angular acceleration will be equivalent to the change in the angular velocity per unit of time.

Later we will use the relationship between linear velocity, radius and angular velocity to find said angular velocity and use it in the mathematical expression of angular acceleration.

The average angular acceleration

$\alpha = \frac{\omega_f - \omega_0}{t}$

Here

$\alpha$ = Angular acceleration

$\omega_{f,i} =$ Initial and final angular velocity

There is not initial angular velocity,then

$\alpha = \frac{\omega_f}{t}$

We know that the relation between the tangential velocity with the angular velocity is given by,

$v = r\omega$

Here,

r = Radius

$\omega$ = Angular velocity,

Rearranging to find the angular velocity

$\omega = \frac{v}{r}}$

$\omega = \frac{30}{0.20} \rightarrow$ Remember that the radius is half te diameter.

Now replacing this expression at the first equation we have,

$\alpha = \frac{30}{0.20*6}$

$\alpha = 25 rad /s^2$

Therefore teh average angular acceleration of each wheel is $25rad/s^2$

What is the relation between Physical states of solution and solvent

posledela

Explanation:

The solute does not have to be in the same physical state as the solvent, but the physical state of the solvent usually determines the state of the solution. As long as the solute and solvent combine to give a homogeneous solution, the solute is said to be soluble in the solvent.
