Chapter , Problem 8(choose chapter or problem)
Panic escape. Figure 2-24 shows a general situation in which a stream of people attempt to escape through an exit door that turns out to be locked. The people move toward the door at speed \(v_{s}=3.50 \mathrm{~m} / \mathrm{s}\), are each d = 0.25 m in depth, and are separated by L = 1.75 m. The arrangement in Fig. 2-24 occurs at time t = 0.
(a) At what average rate does the layer of people at the door increase?
(b) At what time does the layer’s depth reach 5.0 m? (The answers reveal how quickly such a situation becomes dangerous.)

QUESTION:
Panic escape. Figure 2-24 shows a general situation in which a stream of people attempt to escape through an exit door that turns out to be locked. The people move toward the door at speed \(v_{s}=3.50 \mathrm{~m} / \mathrm{s}\), are each d = 0.25 m in depth, and are separated by L = 1.75 m. The arrangement in Fig. 2-24 occurs at time t = 0.
(a) At what average rate does the layer of people at the door increase?
(b) At what time does the layer’s depth reach 5.0 m? (The answers reveal how quickly such a situation becomes dangerous.)
Question: Panic Escape:Fig.2.24 shows a general situation in which a stream of people attempt toescape through an exit door that turn out to be locked. The people move toward the door at a speedof vs=3.5m/s are each d=0.2m in depth, and are separated by L=1.75m. The arrangement in Fig.2.24occurs at time t=0s. (a) At what average rate does the layer of people at the door increase (b) Atwhat time does the layer depth reach d=5.0m.(Answer reveals how quickly such a situation becomesdangerous. Step by Step Solution:Step 1 of 3:In this question, we need to calculate the rate at which the layer of people at the locked doorincrease to make the situation worse and the time at which the layer of people becomes d=5.0m.Given data:The distance between two persons:The depth of the body:Velocity with which a person moves towards the door:
