A 0.340kg particle moves in an xy plane according to x(t)=15.00+2.00t−4.00t
3
and y(t)=25.00+7.00t−9.00t
2
, with x and y in meters and t in seconds. At t=0.700s, what are (a) the magnitude and (b) the angle (relative to the positive direction of the x axis) of the net force on the particle, and (c) what is the angle of the particles direction of travel?
