A car, starting from rest and travelling from p to q on a straight level road,
where | pq | = 10 000 m, reaches its maximum speed 25 m/s by constant
acceleration in the first 500 m and continues at this maximum speed for the
rest of the journey.
A second car, starting from rest and travelling from q to p, reaches the same
maximum speed by constant acceleration in the first 250 m and continues at
this maximum speed for the rest of the journey.
(i) If the two cars start at the same time, after how many seconds do the
two cars meet ?
Find, also, the distance travelled by each car in that time.

i am trying to use uvast equations to solve this but i cant. can someone help me

1. Draw a diagram - it always helps

2. Write down what you know - in terms of u1=0 u2=0 etc

3. Write down the suvat equations - uvast equations.

4. There is an equation that combines just known quanitities - as a hint it will tell you the acceleration ms^-2
