    Post please help me with this velocity question

    Hi

    everyone

    please help me with this velocity question:
    i got clue how to do it?


    here it is:

    1. if v=5+24t - 3t^2 , where v m/s is the velocity of the body at a time t seconds.

    Determine:
    (i) the expression for distance, S, in metres, m.
    (ii) how far it moves in the interval t=1 sec to t=5 sec.

    v=5+24t - 3t^2

    v = ds/dt =5+24t - 3t^2

    So ds = (5+24t - 3t^2)dt

    s = \int{(5+24t - 3t^2)}dt

    Find the integration to find the expression for s.

    s = 5t + 24t^2/2 - 3t^3/3

    For displacement, find s1 and s2 for two time interval and then s = s2 - s1.
