A ball is thrown at an angle 75° with the horizontal at a
speed of 20 m/s towards a high wall at a distance d. If the
ball strikes the wall, its horizontal velocity component
reverses the direction without change in magnitude and
the vertical velocity component remains same. Ball stops
after hitting the ground. Match the statement of column I
with the distance of the wall from the point of throw in
column II .
Column I Column II
(A) Ball strikes the wall directly (1) 8 m
(B) Ball strikes the ground at x = 12 m (2) 10 m from the wall
(C) Ball strikes the ground at x = 10m (3) 0 m from the wall
(D) Ball strikes the ground at x = 5 m (4) 25 m from the wall
