A particle starts moving from rest from ...

A particle starts moving from rest from a fixed point in a fixed direction. The distance s from the fixed point at a time t is given by `s = t^2+at-b + 17`, where a, b are real numbers. If the particle comes to rest after 5 sec at a distance of s = 25 units from the fixed point, then values of a and b are respeetively
