A 3.00 kg box is moving to the right with speed 10.0m/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)= (6.00N/s^2 )t^2
a) what distance does the box move from its position at t=0 before its speed is reduced to zero?
b) If the force continue to be applied, what is the speed of the box at 4.50s?
