Question

Constants A 2.10 kg box is moving to the right with speed 10.0 m/s on a horizontal, frictionless surface. At t = 0 a horizontal force is applied to the box. The force is directed to the left and has magnitude F(t)=( 6.00 N/s^2 )t^2

If the force continues to be applied, what is the velocity of the box at 3.50 s ?
