A 0.35 kg particle moves in an xy plane according to x(t) = - 17 + 1 t - 5 t3 and y(t) = 18 + 5 t - 10 t2, with x and y in meters and t in seconds. At t = 1.5 s, what are (a) the magnitude and (b) the angle (within (-180°, 180°] interval relative to the positive direction of the xaxis) of the net force on the particle, and (c) what is the angle of the particle's direction of travel?
