With what speed does the ball strike the ground
A ball is thrown straight down from the top of a cliff with a speed of 5 m/s. The cliff-top is 20 m above ground level. Neglect the effects of air resistance.
A) How long is the ball in the air?
B) With what speed does the ball strike the ground?

Cooling water circulates through a water jacket enclosing a housing filled with electronic components. At steady state, water enters the water jacket at 20oC and exits with a negligible change in pressure at a temperature that cannot exceed 24oC.
A researcher reported a correlation of 1.25 between an IQ test and grades in EPY 6214. Which one of the following interpretations is most reasonable?
The partition is now removed, and the water expands to fill the entire tank. Determine the entropy change of water during the process, if the final pressure in the tank is 25 kPa.
A steel pipe of 12-in outer diamer is fabricated from 1/4-in-thick plate by welding along a helix that forms an angle of 25 degrees with a plane perpendicular to the axis of the pipe.
A ball is thrown straight down from the top of a cliff with a speed of 5 m/s. The cliff-top is 20 m above ground level. Neglect the effects of air resistance. With what speed does the ball strike the ground?
Determine the power input, the rate of heat transfer from the compressor, and the isentropic efficiency of the compressor.
Two steel I-beams, each with a mass of 100 kg, are welded together at right angles and lifted by vertical cables so that the beams remain in a horizontal plane. Compute the tension in each of the cables A, B, and C
A sample is introduced into the chamber at 760 torr while the isolated pumps are maintained at 10-6 torr. For a 15 cm diameter opening, what force acts on the valve plate to seal it?
Determine the maximum possible volume flow rate for this pump. Neglect any changes in kinetic energy. Assume that water is an incompressible substance with a density of 1000 kg/m^3.
