Homework Chapter 14 Systems of Particles 1- A 40-lb block B is suspended from a 6-ft cord attached to a 60-lb cart A, which may roll freely on a frictionless, horizontal track. If the system is released from rest in the position shown, determine the velocities of A and B as B passes directly under A. 60 lb B 40 lb

Answers

Answer 1

Both block B and cart A have a velocity of 21.52 ft/s when block B passes directly under cart A.

The potential energy of the system is initially all in the form of gravitational potential energy, which is converted to kinetic energy as the block B falls and the cart A moves. At the moment when block B passes directly under cart A, all the potential energy has been converted to kinetic energy.

First, we can find the gravitational potential energy of the system initially:

PE = mgh = (60+40) lb * 32.2 ft/s^2 * 6 ft = 23,184 ft-lb

Next, we can find the kinetic energy of the system at the moment when block B passes under cart A:

KE = 1/2 mv^2

Since the two objects are connected by a cord, they must have the same velocity at that moment. Let's call this velocity v.

For block B:

KE_B = 1/2 (40 lb) (v^2)

For cart A:

KE_A = 1/2 (60 lb) (v^2)

The total kinetic energy of the system is:

KE_total = KE_A + KE_B = 1/2 (40+60) lb (v^2) = 50v^2

Setting the initial potential energy equal to the final kinetic energy:

PE = KE_total

23,184 ft-lb = 50v^2

v^2 = 463.68 ft^2/s^2

v = 21.52 ft/s (rounded to two decimal places)

Therefore, both block B and cart A have a velocity of 21.52 ft/s when block B passes directly under cart A.

Question 40 options:
a) 15.75%
b) 16.75%
c) 13.75%
d) 12.50%

Answers

The expected return for the asset is 20.25%. To calculate the expected return for an asset, we multiply each possible return by its respective probability and then sum the results.

In this case, the expected return can be calculated as follows:

(0.5 x 0.1) + (0.1 x 0.15) + (0.15 x 0.5) + (0.25 x 0.25)

= (0.05) + (0.015) + (0.075) + (0.0625)

Expected return= 0.2025

To express the expected return as a percentage, we multiply the result by 100:
0.2025 x 100 = 20.25%

explain one argument for and one argument against removing employment laws​

Answers

Employment law is a complex practice area that deals with the rights of both employees and employers. Some cases deal with discrimination, including claims of race, gender, disability, or age bias. Wages, trade secrets, or non-competition agreements may also be at the center of other cases.

However, the average employment lawyer spends much of his or her time counseling clients on how to minimize litigation risks. Employment law is never dull, but just like any other practice area, it does have its downsides.

FOR

Employment law offers interesting work, but it also offers opportunities for growth. There are many firms that specialize solely in employment law, but most litigation firms now practice at least some employment law. Many large corporations have their own staff of employment attorneys.

AGAINST

A lawyer may also have to temper emotions in order to prevent escalating situations into larger problems. It is common for employers to take harassment or discrimination claims very personally. The employer’s desire to be vindicated can sometimes be a roadblock to a resolution.

6-9 $85000
A) The payback period is how many years?
B) Does the project meet the benchmark?

Answers

A) The payback period is 2.8 years. B) Yes, the project meets the benchmark for funding. The payback period is the period of time required for a project to recoup its original capital investment.

If a payback period is given, it means that the project should pay for itself in that many years or less, with the final year considered as the payback year. The American Pharmaceutical Company(APC) has a policy that all capital investments must have a three year or less discounted payback period in order to be considered for funding.

So, it is necessary to calculate the payback period for the given project: Year Cash Flow Cumulative cash flow 0-$270,000-$270,0001-$25,000-$295,0002$55,000-$240,0003$180,000-$60,0004$250,000$190,0005$365,000$555,0006-9$85,000$640,000Calculation of payback period: The sum of the first three years' cash flow is -$270,000 - $25,000 + $55,000 = -$240,000The amount remaining to be paid back at the end of year three is $60,000Payback period = 3 – (60,000/180,000) = 2.8 years.

The project meets the benchmark because the payback period is less than three years.

For each scenario, first label if it creates a producer or a consumer surplus. Then, after you have labeled the scenario, calculate the ensuing surplus. .
Alice is willing to spend $30 on a pair of jeans and has a coupon for $10 off. she purchases a pair of jeans that costs $35 pre-discount

Answers

This scenario creates a consumer surplus because Alice is able to purchase the jeans for a lower price than she was originally willing to spend. Alice will pay $5

The consumer surplus in this scenario can be calculated as follows:

Alice's willingness to pay - Actual price paid = Consumer surplus

$30 - $25 = $5

Therefore, Alice gains a consumer surplus of $5 by using the $10 coupon to purchase the $35 pair of jeans. A consumer surplus occurs when a consumer is willing to pay more for a product or service than the actual market price. In this case, Alice was willing to pay $30 for a pair of jeans, but was able to purchase them for only $25 after using the $10 coupon. This means that Alice gained a surplus of $5 by being able to buy the jeans at a lower price than her initial willingness to pay.
