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? + Bt', where
= 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 ?
a =
A. 15.8 J
B. 40 J
C. 1.5 J
D. 5J
