Q3. During a rugby game a player attempted to score a field goal. The optimum angle he needs to get a conversion is 30°. He kicks the ball 20m from try line at a velocity of 18ms. The height of the bar from the base is 3m. Calculate: a. The maximum height reached by the ball (3) Maximum height (Hmax) Hmax = V? Sinae w projection velocity 29 projection and = 182 sin ²30 18x18x (0.5x05) 24981 Hoek distance (clear crossbar 2x9-81 lock distance and an ground -4.12.84.13 m b. How far from the try line did the ball land? (3) 286-20 = 8.6m Distance travelled by the ball! 26-2*30* So therefore the ball Range CHorizontal) = 60° landed 86m R-V2 Sin e away from the thy line 9 - The ball lands 28.6m Prom it was = 182 Sin 60 - 286m kicked. 9.81 c. Was the conversion successful? Y/N. Show proof of your answer. (hint: calculate height of ball at try line) (4) °
