The position of a particle according to the appropriate coordinate set can be vectorially specified in meters as r = i(sin2πt) -16j(1-e-t/4) + kt2/4 where t is the movement time of particle in seconds after passing its origin. If the mass of the particle is 2,4 kg, calculate the x component of its R force and the magnitude of its resultant force R at time t = 4s.
