A block of ice with mass 4.00 kg is initially at rest on a frictionless, horizontal surface. A worker then applies a horizontal force F to it. As a result the block moves along the x-axis such that its position as a function of time is given by x(t) = at? + Bt³, where a = 0.2 m/s? and B = 0.02 m/s³. Calculate the work done by the force during the first 4.00 s of the motion ? %3D A. 15.8 J B. 40 J C. 1.5 J D. 5 J E. 0.89 J
