A 2.0 kg particle moves along an x axis, being propelled by a wariable force directed along that axis. Its position is given by x = 3.0 m+ (4.0 m/s)t + ct²- (2.0 m/s³)³, with x in meters and in seconds. The factor c is a constant. At t = 3.0 s, the force on the par- ticle has a magnitude of 36 N and is in the negative direction of the axis. What is c?
