Determinate the resultant velocity of an airplane. An airplane flies due west at a velocity of 645 kilometers per hour (km/h). The wind blows from the north at a velocity of 125 kilometers per hour (km/h). What is the plane's resultant velocity?
A large punch bowl holds 3.45kg of lemonade (which is essentially water) at 20.0°C. A 0.33-kg ice cube at-10.2°C is placed in the lemonade. What is the final temperature of the system, and the amount of ice (if any) rema ...
A ball on the end of a string is revolved at a uniform rate in a vertical circle with a radius of .72 meters. If its speed is 4m/s and its mass is .3kg calculate the tension of the in the string when the ball is at the t ...

On the basis of a given load of pulley F g = 4000N, Determine the load of the bearing rope BA. The load should be the basis for the design of the supporting ropes, pulleys and ropes to mount joints A and B. Basically you ...
An elevator is moving upward at 0.96 m/s when it experiences an acceleration 0.35 m/s 2 downward, over a distance of 0.71 m. What will its final velocity be?
A rock of 350 kg is found at the top of a mountain that is 1250-m high. Find the potential energy with respect to the bottom of the mountain (g = 9.8 m/s2)
Determine the value of Henry's law constant, in Pa/(kg/m 3 ) of chlorine for the chlorine-water system. The following equilibrium data at 293 K were reported in the Chemical Engineering Handbook.
A pure and very thin SI slice is placed inside of and in parallel with a parallel-plate capacitor which has a spatially constant electric field. The electron potential energy inside the Si varies linearly with distance i ...
Two soccer players kick a soccer ball back and forth along a straight line. The first player kicks the ball 16 m to the right to the second player. The second player kicks the ball to the left weakly; it only moves 1.7 m ...
