A particle moves in two dimensions. The x-position in meters of a particle as a function of time in seconds is given by x(t) = 3 - 7t + 4t2. The y-position in meters of the same particle as a function of time in seconds is given by y(t) = 1 + 2t +3t2. If the particle's mass is 3.4kg, what force (magnitude and direction) is being applied?
