Practice 2 Step Problems
1. A train begins at rest and begins to accelerate for 30s at a rate of 18.0m/s2. The conductor falls
asleep and the train continues at constant velocity for an additional 20s. What was the total
distance traveled by the runaway train?
2. The conductor of the train has narcolepsy. He wakes up from his sleep attack and panics.
Running around, flailing his arms for 15s, the train travels at a constant velocity of 150m/s.
Ahead, in the distance, there is a damsel in distress tied to the tracks 2600m away. After the 15s
of flailing, the conductor slams on the break, and decelerates at a rate 35m/s2 to a complete
stop in 4s . How far did the train travel during the entire trip? Did the damsel survive?
3. A runner is traveling at a constant rate of 2.1m/s for 60s. Suddenly there is a band of zombie
vampires chasing him and he accelerates at a rate of 1.3m/s2 for 23s. What is the total distance
traveled by the runner?
