As two trains move along a track, their conductors suddenly notice that they are headed toward each other. The figure gives their velocities v as a function of time t as the conductors slow the trains. The figure's vertical scaling is set by vs = 21 m/s.The slowing process begins when the trains are 164.00 m apart. What is their separation when both trains have stopped?
Traffic shock wave. An abrupt slowdown in concentrated traffic can travel as a pulse, termed a shock wave, along the line of cars, either downstream (in the traffic direction) or upstream, or it can be stationary. The figure shows a uniformly spaced line of cars moving at speed v = 27.0 m/s toward a uniformly spaced line of slow cars moving at speed vs = 5.30 m/s. Assume that each faster car adds length L = 13.0 m (car length plus buffer zone) to the line of slow cars when it joins the line, and assume it slows abruptly at the last instant. (a) For what separation distance d between the faster cars does the shock wave remain stationary? If the separation is twice that amount, what are the (b) speed and (c) direction (upstream or downstream) of the shock wave?

If the separation is twice that amount, what are the (b) speed and (c) direction (upstream or downstream) of the shock wave?arrow_forwardUnder which of the following conditions is the magnitude of the average velocity of a particle moving in one dimension smaller than the average speed over some time interval?

- Figure 2-42 shows a simple device for measuring your reaction time. It consists of a cardboard strip marked with a scale and two large dots. A friend holds the strip vertically, with thumb and forefinger at the dot on the right in Fig. 2-42. You then position your thumb and forefinger at the other dot (on the left in Fig. 2-42), being careful not to touch the strip. Your friend releases the strip, and you try to pinch it as soon as possible after you see it begin to fall. The mark at the place where you pinch the strip gives your reaction time. (a) How far from the lower dot should you place the 50.0 ms mark? How much higher should you place the marks for (b) 100, (c) 150, (d) 200, and (e) 250 ms? (For example, should the 100 ms marker be 2 times as far from the dot as the 50 ms marker? If so, give an answer of 2 times. Can you find any pattern in the answers?)arrow_forwardA boy runs for 23 seconds. During the first 10 seconds, his minimum speed is 2.2 m/s, while his maximum speed is 3.1 m/s. During the remaining time, his minimum speed is 3.1 m/s, while his maximum speed is 4.7 m/s. calculate the maximum (least upper bound) on the distance that he runs, in meters.arrow_forwardTwo green anacondas X and Y of length 10 m are moving in the same direction with a uniform speed of 20 kmph, with X ahead of Y. Upon detecting prey, Y decides to overtake X. Thus it accelerates by 1 m/s2, after 50 s the tail of Y slithers past X’s head. Calculate the original distance between the two?arrow_forward
- There is a 250-m-high cliff at Half Dome in Yosemite National Park in California. Suppose a boulder breaks loose from the top of this cliff. (a) How fast will it be going when it strikes the ground? (b) Assuming a reaction time of 0.300 s, how long a time will a tourist at the bottom have to get out of the way after hearing the sound of the rock breaking loose (neglecting the height of the tourist, which would become negligible anyway if hit)? The speed of sound is 335.0 m/s on this day.arrow_forwardIn the design of a rapid transit system, it is necessary to balance the average speed of a train against the distance between station stops. The more stops there are, the slower the train’s average speed. To get an idea of this problem, calculate the time it takes a train to make a 15.0-km tripin two situations: (a) the stations at which the trains must stop are 3.0 km apart (a total of 6 stations, including those at the ends); and (b) the stations are 5.0 km apart (4 stationstotal). Assume that at each station the train accelerates at a rate of 1.1 m/s2until it reaches 95 km/h then stays atthis speed until its brakes are applied for arrival at the next station, at which time it decelerates at - 2.0 m/s2 Assume it stops at each intermediate station for 22 s.arrow_forwardSpeedy Sue, driving at +30.0 m/s, enters a one-lane tunnel. She then observes a slow- moving van 200 m ahead traveling at +2.00 m/s (because it has engine trouble). Sue applies the brakes immediately and accelerates at -3.00 m/s2 to come to a stop. a)Determine the separation distance “s” between Sue’s car and the van as a function of time t, with t = 0 when Sue enters the tunnel. b)Determine the closest separation distance that Sue’s car came to the van.arrow_forward
- Two cars are moving along a straight line AB. Car A starts from rest from point A and moves toward point B The acceleration of car A starts from (0) m/s and increases at a rate of( 2 m/s2/s) ( means a=2t m/s?). Car B starts form B and moves toward A. The acceleration of B starts from (0) m/s' and increases by a rate of (4m/s'/s). Both cars are met at a distance of (2/3) of total AB distance as measured from A.

The belt of one ramp moves at a constant speed such that a person who stands still on it leaves the ramp 64 s after getting on. Clifford is in a real hurry, however, and skips the speed ramp. Starting from rest with an acceleration of 0.37 m/s², he cov- ers the same distance as the ramp does, but in one-fourth the time. What is the speed at which the belt of the ramp is moving?arrow_forward(a) Starting at the position x = 0, you walk in the +x-direction for 6 seconds at a constant speed, then stop for 2 seconds, then turn around and walk back toward the origin at a constant speed for 2 seconds, coming to a stop at a position x = 1 m and waiting there for a second. Assume that t= 0 is the initial time.
