Particle with variable velocity

  1. Dec 7, 2008 #1
    1. The problem statement, all variables and given/known data

    A particle is moving along a straight trajectory. The distance covered by a particle is described by the function S(t)=2t^3+5t^2 , where t>0 is the time.

    What is the distance covered by the particle by the time t=4

    2. Relevant equations

    3. The attempt at a solution

    sub t=4 into the equation we get 2(4)^3+5(4)^2
    =208 plse check fi this is correct??
