A time-varying net force acting on a 5.8kg particle causes the object to have a displacement given by(adsbygoogle = window.adsbygoogle || []).push({});

x = a + bt + dt^2 + et^3

where a = 2m, b = 1.8 m/s, d = -1.6 m/s^2, e = .94 m/s^3 with x in meteres and t in seconds. Find the work done on the partciel in the first 4.4 seconds of motion. Answer in units of J.

i've taken both derivative and integral, im not getting any way correct grr. can someone help
