Two-part kinematics problems:

21.  A dragon accelerates from 1.13 m/s to 3.60 m/s in 4.13 seconds.  Over what distance could it accelerate from rest to 6.85 m/s if it had the same acceleration?  Solution

22. A car accelerates uniformly from rest, covering 65.0 m in 5.62 seconds.   What time would it take the same car to go from 8.90 m/s to 29.4 m/s if it had the same acceleration?  Solution

23. A runner covers 21.5 m accelerating uniformly from rest to 9.94 m/s.  What was their speed when they had covered only 13.0 m?  Solution

24. A train decelerates from 35.0 m/s to 22.0 m/s in 42.0 seconds.  What time did it take it to cover 98.0 meters from the beginning?  Solution

25. A car accelerates from rest to 23.0 m/s over a distance of 231 m.  What time would it take it to accelerate from rest to 20.0 m/s if it accelerated at the same rate?  Solution
