You have been hired as a technical consultant for an early-morning cartoon series for children to amke sure that the science is correct. In the script, a wagon containing two boxes of gold (total mass of 150kg) has been cut loose from the horses by an outlaw. The wagon starts from rest 50 meters up a hill with a 6 degree slope. The outlaw plans to have the wagon roll down the hill and across the level fround and then crash into a canyon where his confederates wait. But in a tree 40 meters from the edge of the canyon wait the lone ranger (mass 80kg) and Tonto (mass 70kg). They drop vertically into the wagon as it passes beneath them. The script states that it takes the lone ranger and tonto 5 seconds to grab the gold and jump out of the wagon, but is this correct? You assume that the wagon rolls with negligeble friciton.

Discuss the similarities and distinctive features of early HTML versions (e.g., HTML 4.01) and the contemporary HTML 5 which is universally accepted and recommended currently for web developers to use. What advantages (and possible disadvantages) may HTML 5 provide when developing specific websites? When might it be appropriate to use XHTML and when and why would it not be appropriate? Compare HTML 5 with XML and one or more other mark-up languages.

Find at least two websites that illustrate your view. Justify your answer.

1. The first bitcoin transaction was conducted on January 12th 2009. In its early days, the value of bitcoins were practically zero (In March 2010, a user auctioned 10,000 bitcoins for a total of $50 but no buyer was found.) By December 17th, 2017, the price of bitcoin has reached an all-time high of $19,783. As of today (March 12, 2019), its price is $3,858.

a. In what ways is bitcoin similar to a Ponzi scheme?

b. In what ways is bitcoin different?

Lone Star Sales & Service acquired a new machine that cost $84,000 in early 2016. The machine is expected to have a five-year useful life and is estimated to have a salvage value of $14,000 at the end of its life. (Round your final answers to the nearest dollar.)

(a.) Using the straight-line depreciation method, calculate the depreciation expense to be recognized in the second year of the machine's life and calculate the accumulated depreciation after the third year of the machine's life.
(b.) Using the double-declining-balance depreciation method, calculate the depreciation expense for the third year of the machine's life and the net book value of the machine at this point in time.  

An instrument used to measure the airspeed on many early low-speed airplanes was a venturi duct with a convergent-divergent duct (the front section's cross sectional area decreases in the flow direction, and the back section's cross sectional area increases in the flow direction. There is a "throat" in which the area is minimum.). Let A1 and A2 denote the inlet and throat areas, respectively. Let P1 and P2 denote the pressure at the inlet and throat, respectively. If the area ratio is A2/A1 = 1/4 and P1 - P2 = 80 lb/ft2. If the aircraft is flying at standard sea level, what is the velocity in knots?

In early January 2017, NewTech purchases computer equipment for $273,000 to use in operating activities for the next four years. It estimates the equipment’s salvage value at $26,000.
