when t = 0, a particle at (1,0,0) moves towards (4,4,12) with a constant velocity of magnitude of 65 m/s. the position of the particle is measured in meters and time in sec. Assuming constant velocity the position of the particle at t= 2 sec is
(a) (13 – 120 +40) m
(b) (40 +31– 120) m
(c) (13 – 40 + 12) m
(d) (31 + 40+ 120) m
