#1 with complete solution
1. A car is accelerating uniformly as it passes two checkpoints
that are 38m apart. The time taken between checkpoints is
6.4s and the car's speed at the first checkpoint is 6.7m/s.
Find the car's acceleration and its speed at the second
checkpoint?
2. A bus travels 400m between two stops. It starts from rest
and accelerates at 1.5m/s² until it reaches a speed of 9m/s.
The bus continues at this speed and then decelerates at
2m/s² until it comes to stop. Find the total time required for
the journey?
