A commuter train travels between two downtown stations. Because the stations areonly 1.00 km apart, the train never reaches its maximum possible cruising speed.During rush hour the engineer minimizes the time interval Δt between two stations byaccelerating at a rate = 0.100 m/s2for a time interval Δt1 and then immediately brakingwith acceleration = —0.500 m/s2for a time interval Δt2. Find the minimum timeinterval of travel Δt and the time interval Δt1

Question

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 time interval Δt between two stations by
accelerating at a rate = 0.100 m/s
2
for a time interval Δt1 and then immediately braking
with acceleration = —0.500 m/s
2
for a time interval Δt2
. Find the minimum time
interval of travel Δt and the time interval Δt1
