A ball is thrown straight down with a velocity of 12 m/s; what will be its velocity 2.0 s after being released?

hichkok12 [17]

Answer:

$v = 31.6m/s$

Explanation:

Given

$Initial\ Velocity, u = 12m/s$

$Time, t = 2.0s$

Required

Determine the final velocity, v

Using the first equation of motion

$v = u + at$

But in this case;

a = g = acceleration of gravity

So:

$v = u + gt$

Substitute values for u and t

$v = 12 + g * 2$

$v = 12 + 2g$

Take g as 9.8m/s²

$v = 12 + 2 * 9.8$

$v = 12 + 19.6$

$v = 31.6m/s$

<em>Hence, the velocity is 31.6m/s</em>

A 24000- railroad freight car collides with a stationary caboose car. They couple together, and 22 percent of the initial kineti

Klio2033 [76]

Answer:

$m_{c} = 6768\,kg$

Explanation:

According to the Principle of Energy Conservation and the Work-Energy Theorem, the system is modelled as follows:

$K_{o} = K_{f} + W_{loss}$ , where $\frac{K_{f}}{K_{o}} = 0.78$ .

Then,

$K_{f} = 0.78\cdot K_{o}$

$0.5\cdot (m_{f}+m_{c})\cdot v_{f}^{2} = 0.39\cdot m_{f}\cdot v_{o}^{2}$

Besides, the Principle of Momentum Conservation describes the following model:

$m_{f}\cdot v_{o} = (m_{f}+m_{c})\cdot v_{f}$

The final velocity of the system is:

$v_{f} = \frac{m_{f}}{m_{f}+m_{c}}\cdot v_{o}$

After substituting in the energy expression:

$0.5\cdot \frac{m_{f}^{2}}{m_{f}+m_{c}}\cdot v_{o}^{2} = 0.39\cdot m_{f}\cdot v_{o}^{2}$

$0.5\cdot m_{f} = 0.39\cdot (m_{f}+m_{c})$

The mass of the caboose is:

$0.39\cdot m_{c} = 0.11\cdot m_{f}$

$m_{c} = 0.282\cdot m_{f}$

$m_{c} = 0.282\cdot (24000\,kg)$

$m_{c} = 6768\,kg$

An ice skater is in a fast spin with her arms held tightly to her body. When she extends her arms, which of the following statem

Genrish500 [490]

Answer:

A. Her total angular momentum has decreased

Explanation:

Total angular momentum is the product of her moment of inertia and angular velocity. In this scenario it doesn’t decrease but rather remains constant as the movement of the arms doesn’t have any effect on the total angular momentum.

The movement of the arm under certain conditions however has varying effects and changes on parameters such as the moment of inertia and the angular speed.

Your teacher wants you to perform an experiment that will demonstrate a chemical property. Which experiment should you choose? A

Dovator [93]

A) Measure the pH of different household chemicals

Explanation:

To demonstrate a chemical property using an experiment, measuring the pH of different household chemicals will be the best way. The pH is the degree of hydrogen or hydroxyl ion concentration in a solution.

Chemical properties tell us about what a substance can do.
It shows if a substance will react with other substances or not.
Examples are flammability, rusting of iron, precipitation, decomposition of water by electric current e.t.c.
Measuring the pH is a chemical property determination procedure.
The pH points to the degree of acidity or alkalinity of a solution.
