(a) If the maximum acceleration that is tolerable for passengers in a subway train is 1.54 m/s2 and subway stations are located 836 m apart, what is the maximum speed a subway train can attain between stations? (b) What is the travel time between stations? (c) If a subway train stops for 21.0 s at each station, what is the maximum average speed of the train, from one start-up to the next?

a train with a maximum speed of 60mph travels between two stations 5,192 ft apart. It has an acceleration rate of 4 ft/s^2 and requires a distance of 1584ft to stop from 60 mph. Sketch (a) acceleration- time, (b) velocity-time, (c) displacement-time diagrams and (d) determine the minimum running time between stations in seconds. Note: Train stops at all stations. Show all working out. (d) tmin =?
A subway train starts from rest at a station and accelerates at a rate of 1.60 m/s2 for 10.0 s
A subway train starts from rest at a station and accelerates at a rate of 1.60 m/s2 for 10.0 s. It runs at a constant speed for 50.0 s and slows down at a rate of 3.20 m/s2 until it stops at the next station. How far apart are the two subway stations? A 40 m B 80 m C 800 m D 920 m E None of the above.

. Movement of a train. A train starts from a station A and has a constant acceleration of 0.4 for 2 minutes.for the next 75 seconds it continues with constant speed, and finally applies the brakes until it stops at station B due to a deceleration of 0. 8 m / s2. (a) Calculate the distance between stations A and B. (b) Prepare the graphs Position (x) - time (1), speed (v) - time (() and acceleration (a) - time...

rw n8.00-09:15 - HY 2053 Test #1 2019-01-30 1. A subway train starts from rest at a stat ion and accelerates at a constant acceleration of a 2.85 m/2 for 22.3 s. It then travels at a constant speed for 62.0 s and th at a constant acceleration o f a2 = 3.75 A until it stops at the next station. Find the total distance covered by the subway train for this trip

A commuter train travels between two downtown stations. Because the stations are only 1.00 km apart, the train never reaches its maximum possible cruising speed. During rush hour the engineer minimizes the travel interval Δt between the two stations by accelerating for a time interval Δt1 at a1 = 0.100 m/s2 and then immediately braking with acceleration a2 = -0.360 m/s2 for a time interval Δt2. Find the minimum time interval of travel Δt and the time interval Δt1. Hint:...

1. A 25,000-kg subway train initially traveling at 20 m/s slows to a stop in a station and then stays there long enough for its brakes to cool. The station's dimensions are 65 m long by 20 m wide by 15 m high. Assuming all the work done by the brakes in stopping the train is transferred as heat uniformly to all the air in the station, by how much does the air temperature in the station rise? Density kg/m2....

Problem 5: The greatest possible acceleration or deceleration that a train may have is a and its maximum speed is v. Find the minimum time in which the train can get from one station to the next if the total distance between the stations is s. Assume the train starts from the first station at rest and stops when it reaches the next station.
