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) (13i – 120j +40k) m (b) (40i +31j – 120k) m (c) (13i – 40j + 12k) m (d) (31i + 40j + 120k) m
