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
