1.	A ball is projected from a certain point on the surface of a planet at a certain angle with the horizontal surface The horizontal and vertical displacement x and y varies with time t in second as: x = 10root3t and y = 10t -t ^2 The maximum height attained by the ball is (A) 100 m (B) 75 m (C) 50m (D) 25 m.
Answer» a ball is projected from a CERTAIN point on the SURFACE of a Planet at a certain ANGLE with the horizontal surface. the horizontal and vertical displacement X and Y vary with time t in SECOND as : x=10√3 and y=10t-t^2 .
