A projectile is shot from the edge of a cliff at an initial speed of 5.0 m/s at angle 30o with the horizontal. After 12 seconds, the projectile hits the ground below at some point P. (a) Determine the height of the cliff above ground level. (b) Determine the distance of the point P from the base of the vertical cliff. (c) At the instant just before the projectile hits point P, find the horizontal and the vertical components of its velocity

Suppose a TCP client needs to send 3 packets to the TCP server. Before sending the first packet, the estimated RTT is 50 ms, and the estimated deviation of the sample RTT is 10 ms. The parameters α= 0.1, and β = 0.2. The measured sample RTT for the three packets are 60ms, 70 ms, and 40 ms, respectively. Please compute the time out value that was set for each packet right after it is being transmitted out.

Write a C function to swap the first and last elements of an integer array. Call the function from main() with an int array of size 4. Print the results before and after swap (print all elements of the array in one line). The signature of the arrItemSwap() function is:

void arrItemSwap(int *, int, int); /* array ptr, indices i, j to be swapped */

Submit the .c file. No marks will be given if your pgm does not compile and run.

The urban tram project, which operates with a light rail system, is planned. In addition to metaformic, sedimentary and magmatic rocks on the ground, unconsolidated fine sand-silt grain size ground materials were also found. Underground water level depth is between 1 and 3 meters. There is a fault zone along the project line. What can be the geotechnical problems that may be encountered before, during and after the project construction, and solutions as a civil engineer?

On a frictionless horizontal air table, puck A (with mass 0.245 kg ) is moving toward puck B (with mass 0.373 kg ), which is initially at rest. After the collision, puck A has velocity 0.118 m/s to the left, and puck B has velocity 0.647 m/s to the right.

a. What was the speed vAi of puck A before the collision?

b. Calculate ΔK, the change in the total kinetic energy of the system that occurs during the collision.

two skaters collide and embrace, in a completely inelastic collision. boomer, whose mass is 83 kg, is originally moving east with v=6.2km/hr. sooner whose. mass is 55kg, is originally moving north with v=7.8km/hr. (a) what is the velocity of the couple after impact? (b) what is the velocity of the center of mass of two skaters before and aafter collision? (c) what is the fractional change in the Kinect energy of the skaters because of the collision?

A plant manufacturing nails and screws uses a large pool (volume = 10,000 L) to collect and treat its residual wastewater before discharging it in a nearby stream. The manufacturing process makes use of a strong acid (HCl) and a weaker one (phosphoric acid, H₃PO₄; pK_a1 = 2.148, pK_a2 = 7.20, pK_a3 = 12.15), before discharging them in the pool for treatment (neutralization). Once the pool is filled to its maximum capacity, a technician measures the chlorine and phosphorus concentrations in the wastewater to be 0.5 M and 1.0 M, respectively. Assume (i) that chlorine and phosphorus come only from HCl and phosphoric acid, respectively, and (ii) that no H⁺ was consumed (or neutralized) in the manufacturing process.

Knowing that the technician has to bring the pH of the waste water back to a minimum of 7.2 before discharging it in the stream, what is the minimum amount (in kg) of NaOH_(s) (40 g/mol) that he has to add to the pool before discharging the waste water in the stream?

What will be the pH of the wastewater following the addition of 200 kg of NaOH to the initial wastewater?

What will then be the number of moles of each phosphorus species (H₃PO₄, H₂PO₄^-, HPO₄^2- and PO₄^3-) in the pool after the addition of NaOH?

What will be the pH of the wastewater if the technician adds 10.0 kg of NaOH in excess to what is needed to bring the pH to 7.2?

Assume that you were given an opportunity to purchase a real estate project using an equity participation loan. The NOI for each year of the holding period are shown below: 2 Annual payments are being used to make the problem easier!

NOI :

Year 1 124,787

Year 2 132,225

Year 3 139,954

Year 4 148,468

Additional information:

1) Purchase price = $1,900,000

2) Estimated value of land = $500,000

3) Anticipated mortgage terms: a) Loan to value ratio = .80 b) Interest rate = 5.5% c) Years to maturity = 30 d) Points charged = 2 e) Prepayment penalty = 2% of outstanding balance f) Level payment, fully amortized g) Fixed interest rate, monthly payments

4) Participation terms: a) Share of NOI = 15.0% over $125,000 b) Share of Appreciation = 20%

5) Future sales price = $2,150,000

6) Estimated selling expenses as proportion of future sales price = 5%
