ILL-ADDICTOn APP - 12 marks) 1. When a ball is thrown, the horizontal distance travelled, d, in metres, can be modelled by the equation d = sin 20, where g - 9 8-, v is the velocity with which the ball is thrown, in metres per second, and ? S is the angle of elevation, in radians. If a ball is thrown at 40 m/'s. what angle of elevation is required for the ball to travel 40 m
