V3 A train is moving on a straight track with an acceleration of 2.5 m/s2.A projectile is thrown from a point on thefloor of the train (assumed as origin in the train reference frame) at an elevation of T4 and with an initial velocity of 4m/s. The projectile is found to hit the floor at a distance of 1.6 m from the origin . Determine the angle between the position vector of the projectile when it returns to the direction of motion of the train. (A) cos(-1/8) (B) cos(-1/6) (C) cos'(-1/4) Particles A and B are moving with constant velocities along x and y axis respectively, the (D) cos(-1/2) A
