Q) A body with a mass of 15 kilograms is moving with a velocity of 3 meters/secand. If a force of 15 N is applied to the body, what its velocity aller 5 socunds? discuss your results please.
How much energy would it take to raise a can of soda (m = 350 grams) to average cruising altitude (35,000 ft)? Our textbook states that a gallon of gasoline contains 1.2×108 Joules of energy. Assuming 100% efficiency, how many gallons of gasoline would it take to raise the can of soda to 35,000 ft? A calorie is the amount of energy needed to raise the temperature of 1 gram of water by 1 Celsius degree (4.186 J). A nutritional Calorie is actually 1000 calories (1 Cal = 1 kcal). How many Calories of energy does it take to raise the can of soda to cruising altitude? Given that a can of Coke is about 140 Calories, how many cans of coke does it take to raise a can of coke to cruising altitude?

As a young engineer, you have been tasked to select the location of a wind turbine based on the details of the location and relevant specification below:Air densityAverage air velocityDiameter of wind turbine bladesLOCATION A1.29 kg/m3 54 km/h 70 mLOCATION B1.21 kg/m3 63 km/h 60 m By comparing the amount of power generated (in MW) at Location A and Location B, determine the location that will give the optimum wind power generation.9 kg of Refrigerant 134-a is initially at 26.69°C with enthalpy of 100 kJ/kg. Heat is transferred to the refrigerant under a constant-pressure process until the entropy of the refrigerant reaches 0.9795 kJ/kg.K.(i) Determine the final temperature of the refrigerant(ii) Calculate the boundary work, Wb, in kJ.Assist your answer with a proper P-v diagram indicating the properties,process, and boundary work region clearly.(iii) Explain the reason behind the high amount of boundary work obtained in (ii).Assist your explanation with relevant sketching.
You are working in a machine tool manufacturing industry for the project to design CNCcontrol shaper machines. In the shaper machine, a rectangular plate of 8.75 m2area hasto move slowly at a constant speed of 20 mm/minute over a fixed plate. The distancebetween the moving and fixed table is 0.0254 mm, and the gap is filled by a fluid ofviscosity 8.17 × 10−5 N−sm2. Calculate the amount of force required to move the plate.
What is the equation for the time of flight of a projectile? Is this equation dimensionally homogeneous?
7. Saul ascends from the city of Tucson, Arizona to the top of Kitt Peak, 2900 m above the sea level. Usually, Saul will feel his ears “pop” as the pressure inside his ears attempts to maintain the equilibrium with the surrounding air. However, on this day Saul has cold and his Eustachian tube is clogged, causing a tremendous pressure behind his 4.0×10^(-5) m^2 ear drum. What force does Saul feel pushing on his ears? (D_air=1.20 kg/m^3) a. 0.50 N b. 0.05 N c. 0.12 N d. 0.08 N e. None of the above
Most of you have seen car advertisements where the car manufacturerbrags about how fast one of its cars can go from 0 to 100 km/h. Accordingto the manufacturer, the BMW 750iL model can go from 0 to 100 km/h in6.7 seconds. This performance is usually measured on a test track. The engine in the car is rated at 243 kW at 5000 rpm. The car has a reported weight of 23 kN . Is the claim by the manufacturer justifiable? Well, to answer this question you may agree it would be more fun to drive toa BMW dealership and take the car for a test run on a racing track. But let us answer this question with the knowledge you have gained so far in this course. We need to make some assumptions first; we can assume that the driver weighs 900 N and the reported weight of the car includes enough gasoline for this test. Next, we convert the speed and the mass values into appropriate units.
What power in KW is required to lift a 1500 kg mass a distance of 80 m in 14 sec? The correct answer is 84.09 KW
A 1000 kg spacecraft is approaching Jupiter (which is at the origin). The position of the spacecraft is given by the vector RSC = (0.0,-2.533) x 106km. The velocity is given by VSC= (+6.00, +8.00) km/sec. The mass of Jupiter, (MJ=318 MEarth) and MEarth = 5.97 x 1024 kg. A) What is the potential and kinetic energy of the spacecraft (write each to 3 sig figs.) What is the total energy of the spacecraft? Call the total energy Ei. B) Can it escape Jupiter? Justify your answer. C) What is the angular momentum of the spacecraft around Jupiter? Call this Li.
To apply conservation of momentum to describe the motion of a rocket. A rocket is launched into deep space, where gravity is negligible. In the first second, it ejects 1/160 of its mass as exhaust gas and has an acceleration of 16.0 m/s2. What is vg, the speed of the exhaust gas relative to the rocket?
A parachutist has a terminal velocity of -176 feet per second. That is, no matter how long a person falls, his or her speed will not exceed 176 feet per second, but it will get arbitrarily close to that value. The velocity in feet per second, v(t), after t seconds satisfies the differential equation v′(t) = 32 - k *v(t). What is the value of k?
