Problem 93

A playground slide is in the form of an arc of a circle that has a radius of 12 m. The maximum height of the slide is h = 4.0 m, and the ground is tangent to the circle (Fig. 8-68). A 25 kg child starts from rest at the top of the slide and has a speed of 6.2 mls at the bottom. (a) What is the length of the slide? (b) What average frictional force acts on the child over this distance? If, instead of the ground, a vertical line through the top of the slide is tangent to the circle, what are (c) the length of the slide and (d) the average frictional force on the child?

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
