A simple Management software has to be built within 60 days of time in which simple user requirements are told by client. Which model will be best appropriate for developing this kind of software? 

To prove your knowledge as transmission planning engineer in AIT telecom Unit, you are show that values of U which approaches one (1) brings about delay. Analyze this by a delay curve or graph. Choose values of U from 0.0 to 1.0 and D from 1 to 10.

please read and answer correctly , also help with the sketch of the graph, thanks

A metal car starts from rest and slides 12 m down a chute that is inclined at 40° to the horizontal. It then continues to slide along a horizontal length of the chute and eventually comes to rest. If μ = 0,2 between the chute and the car, calculate the horizontal length of the chute. Use conservation of energy to solve this question.

A tractive effort of 3kN drives a 5 ton truck from rest up an inclince of 1 in 40. If the tractive resistance is constant at 380N and the tractive effort is parralel to the plane of the incline, use the method of conservation of energy to calculate the speed of the trcuk after it has traveled 250m up the incline.

Clearly show the following values:

E_k=?

E_p=?

E_TR=?

E_TE=?

Energy equation=?

v=?

A train of mass 220 tonnes starts from rest up a grade of 1 in 90 incline. It reaches a speed of 72 km/hr in a distance of 900 m (up the incline). The acceleration is uniform and the tractive resistance is 0,75 % of the weight of the train. Use Newton’s second law to calculate the tractive effort required.

During your calculations clearly show:
