(a) Figure Q1 (a) shows a basketball game. Player A is trying to shoot the ball from point A, at 60∘ angle with distance 5.6 m from the hoop. The hoop is 3 m off the ground. Neglect the size of the ball. Use g=9.81 m/s2. (i) Determine the velocity, VA​, required for the ball to enter the hoop if the ball is shoot at 2.X metres off the ground, where X is the last non-zero digit of your matric number. For example: if your matric number is AN201050, point A=2.5 metres off the ground. (6 marks) (ii) The player playing defence, intends to block the ball at point B. He makes a jump at 60∘ angle from the floor at the exact same time the ball is shot at A. Calculate the height of point B from the ground, h, if the horizontal distance from the hoop is 0.Xm, where X is the last non-zero digit of your matric number. For example: if your matric number is AN201050, point B=0.5 metres from the hoop. (4 marks) (iii) Calculate the magnitude and direction of velocity of the ball when it contacts player B's hands.
