A ball is projected at an angle of 53° with a speed of 20 m/s towards a wall as shown in figure. Ball rebounds such that component of its velocity perpendicular to wall reverses without change in its magnitude while the component of its velocity parallel to the wall remains same. Consider no time lapse in collision. The average acceleration (in m/s²) of the ball throughout the motion (ABC) is 4 B
