. A 2.0 kg particle is moving along the x axis to the left with a velocity of v= 6.0 m/s. Suddenly, between times t =0 and t = 4.0 x a net force = 3t^2 – 12t is applied to the particle, where F is in N and t is in s. Calculate the velocity of the particle at t=4.0 s. Please show how to answer this problem. Thanks
