Problem 17

Water skiers often ride to one side of the center line of a boat, as shown in Figure 715. In this case, the ski boat is traveling at 15 m/s and the tension in the rope is 75 N. If the boat does 3500 J of work on the skier in 50.0 m, what is the angle between the tow rope and the center line of the boat?

Step-by-Step Solution:
Step 1 of 3

Chapter 17: Phases and Phase Changes  An ideal gas is one that is dilute enough, and far away enough from condensing, that the interactions between molecules can be ignored  If the volume of an ideal gas is held constant, we can find that the pressure increases with temperature o P = (constant)T  If the volume and temperature are kept constant, but more gas is added, the pressure will increase o P = (constant)N  If the temperature is constant and the volume decreases, the pressure increases o P = (constant) / V  Combining all of the above equations, we create the following equation o P = k (NT/V) o K = the Boltzmann constant = 1.38 x 10^(­23) J/K o PV=NkT
