A 2.40 kg box is moving to the right with speed 9.00 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 magnitudeF(t)=( 6.00 N/s2 )t2

a). What distance does the box move from its position at t=0 before its speed is reduced to zero?

b). If the force continues to be applied, what is the velocity of the box at 5.00 s ?
