A student wants to kick the soccer ball into a 3rd floor window, located 3 [m] above from the ground level. The student kicks the ball at a speed V₁. What is the speed for the soccer ball to reach the 3rd floor? what is angle? Also, what kinetic energy or potential energy if the ball weight 500 g ? Also find work? da 3rd foor window - 2M

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.

airplane p have horiztonal velocity v=500 km/h, increasing at rate of 10m/s. for radar tracking at O. find the value of ( r dot), (theta dot) and (theta double dot) for the instant. please show FBD and clear work.

A professional baseball pitcher can project a baseball atca speed as high as 35 m/s. 1.If air resistance can be ignored, how high in metres would a baseball launched at this speed rise if projected straight up? 2.How long would the baseball be in the air (in seconds)

We define the specific ideal gas constant Rgas for a particular gas as the ratio of the universal gas constant and the molar mass (also called molecular weight) of the gas, Rgas = Ru/M. For a particular gas, then, the ideal gas law is written as follows:                                                                                              PV = mRgasT  or  P = ρRgasT where P is pressure, V is volume, m is mass, T is absolute temperature, and ? isthedensityoftheparticulargas.Whatare the primary dimensions of Rgas? For air, Rair = 287.0 J/kg·K in standard SI units. Verify that these units agree with your result.

A correlation of computational fl uid dynamics results indicatesthat, all other things being equal, the distance traveledby a well-hit baseball varies inversely as the 0.36 power ofthe air density. If a home-run ball hit in Citi Field in NewYork travels 400 ft, estimate the distance it would travel in( a ) Quito, Ecuador, and ( b ) Colorado Springs, CO.

What is the relationship between the pressure and the volume of air in cartesian diver?

A milkshake has fairly similar density to that of water (m s = 1200 kg/m3) but is far more viscous ( = 1kg/m
s) (a) Say you try to drink a milkshake through a straw that is 30 cm long and 5 mm in diameter. Your lungs are capable of creating a vacuum pressure of 3000 Pa. (Vacuum pressure just means a pressure below that of the atmosphere, so plung = patm  3000 Pa.) You Önd that if you place the straw just at the surface of the liquid, you are unable to suck the milkshake through the straw, but if you push the straw deeper into the shake, you can. To what depth, d, would you need to push the straw in order to just start to sip the milkshake?(b) Suppose you push the straw to a depth of 10 cm and suck with a suction pressure of 3000 N/m2. What volume áow rate of milkshake can you produce through the straw

The 300-meter radiotelescope in Arecibo, Puerto Rico(Fig. 25–33), is the world’s largest radiotelescope, butmany other radiotelescopes are also very large. Why areradiotelescopes so big? Why not make optical telescopesthat are equally large? (The largest optical telescopes havediameters of about 10 meters.)

The velocity field of a flow is described by                                                        V-›= (4x) i-›+ (5y + 3) j-›+ (3t2)k-›.                                                                        What is the pathline of a particle at a location (1 m, 2 m, 4 m) at time t = 1 s?
