At t = 0 a projectile is fired from a point O(taken as origin) on the ground with a speed of 50 m/s at an angle of 53° with the horizontal. It just passes two points A & B each at height 75 m above horizontal as shown. Q.6 The horizontal separation between the points A and B is (A) 30 m (B) 60 m (C) 90 m (D) None Q.7 The distance (in metres) of the particle from origin at t = 2 sec. (A) 60√2 (B) 100 (C) 60 (D) 120
