. You have constructed a pendulum by tying a 760 g mug to a 73 cm string. You pull the mug 21 degrees to the side, then you release it. a) Draw an illustration of the pendulum, labeling all information known. b) What are the kinetic and potential energy at the top and bottom of the swing? c) What is the work done by gravity from top to bottom of the swing? d) What is the work done by the string from the top to the bottom of the swing? e) Assuming negligible air resistance, what is the mug’s speed when its at the lowest point in its swing? f) Draw the free-body diagram for the mug when the string is 10 degrees from vertical. g) What is the mug’s radial and tangential acceleration when the string is 10 degrees from vertical? h) What is the tension in the string when the mug is at the bottom of its swing? i) At what angle is the tension in the string equal to the weight of the mug?

Expert Solution

Keeping in mind the point of conservation of energy we can solve above problem easily.

work done by tension force in string will be zero due to its perpendicular displacement.

You have two mutually exclusive projects A and B and have constructed the NPV profiles for these projects. You find that the IRR of A is greater than the IRR of B but at an 8% cost of capital using the NPV method you would prefer project B. What is causing the NPV profile pattern that you are observing? Which project do you prefer and why? Essentially you are preferring one method over another so you need to discuss the...

A new warehouse is to be constructed and you have been tasked to provide the initial design. The warehouse is primarily used for pick/pack of grocery items with a small amount of frozen goods and some pharmaceuticals. Incoming goods are palletized and outgoing orders are as per the customers’ orders. The warehouse will contain some 8000 SKU’s with the majority considered, 80%, to be C class items. The building is only framed right now and is waiting on your design...

In a recent year, the Better Business Bureau settled 73% of complaints they received. You have been hired by the Bureau to investigate complaints this year involving computer stores. You plan to select a random sample of complaints to estimate the proportion of complaints the Bureau is able to settle. Assume the population proportion of complaints settled for the computer stores is 0.73, as mentioned above. Suppose your sample size is 190. Please answer the following questions, and show your...

You measure 40 textbooks' weights, and find they have a mean weight of 73 ounces. Assume the population standard deviation is 4.7 ounces. Based on this, construct a 95% confidence interval for the true population mean textbook weight. Give your answers as decimals, to two places I am 95% confident that the mean weight of textbooks is between and ounces.
