A 4.1kg block moving along the x axis is acted upon by a single horizontal force that varies with the block's position according to the equation F_x = ax^2 + b, where a = 8 N/m^2, and b = -2.8 N. At 1.5 m, the block is moving to the right with a speed of 4.3 m/s. Determine the speed of the block at 2.8 m.(adsbygoogle = window.adsbygoogle || []).push({});

do i have to just integrate that formula?
