An asset has an initial cost of $45,000 at the end of 4 years the salvage value of the asset is $5,000. Using the sum of the years' digits, calculate the accumulated depreciation at the end of the 4 years.
Using the same asset presented in problem above . Apply the sum of the years' digits to calculate the depreciation only in year 2.
A 0.20 kg stone attached to a 0.8 m long string is rotated in a horizontal plane. The string makes an angle of 25° with the horizontal. Determine the speed of the stone.
Determine whether these conditions are true or false.
In an unconfined aquifer having K = 30/m/day, two observation wells, 3km apart, have water levels of 50 and 40 m, respectively, above the base of the aquifer. Determine the rate of flow.
If the ball strikes the side of the building 2s after being thrown, at what height above the base of the building did the ball strike the building? What is the velocity of striking?
An equal-tangent crest vertical curve has a 50 mi/h design speed. The initial grade is +3%. The high point is at station 33+37.43 and the PVT is at station 37+18.26. What is the elevation difference between the high point and the PVT?
What is the risk of constructing a harbor which will be unprotected from wave attack during its construction.
A falling-head permeability test was carried out on a clay soil of diameter 100 mm and length 150 mm. In 4 minutes the head in the standpipe of diameter 5mm dropped from 680 to 350 mm.
