Such a player knows that she/he should properly adjust theangle of projection () of the ball when the ball is released with a certain velocity, u.This adjustment has to be done so that the vertical distance, travelled by the ball,in a time to, equals the vertical separation between the basket and the point ofprojection. Also, in the time to, the ball should travel a horizontal distance equal tothe horizontal separation between the basket and the point of projection.(1)For a given speed of projection, the horizontal distance, covered by the ball, hasits maximum value when the angle of projection equals :(a) 45°(b) 90°(c) 30°(d) 60° |
