Please help with the following calculus question:

A particle is moving along straight line and its position at time i (measured in seconds) is given by 3(t):5t2+a-t where a. E R is a constant. Suppose that the particle's initial velocity is 10 {meters/second). i.e.. s' (0) : 10. Then the TOTAL DISTANCE the particle has traveled from time t=0 to time t=3 equals 025
