Atime-varying net force acting on a 2.6 kg particle causes the object to have a displacement given by x = a + b t + d t2 + e t3 , where a = 1.1 m , b = 1.8 m/s, d = −3.1 m/s 2 , and e = 1.1 m/s 3 , with x in meters and t in seconds. find the work done on the particle in the first 4.4 s of motion. answer in units of j.

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
