Part D - Application [APP - 12 marks] 1. When a ball is thrown, the horizontal distance travelled, d, in metres, can be modelled by the equation V 2 d = - sin 20, where g = 9.8-7, v is the velocity with which the ball is thrown, in metres per second, and 0 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? vvVV 2. A triangular ramp is built with an incline angle of -. If the base of the ramp is 1 m in length, determine the exact value for the height of the ramp. Show all steps. vvVV Page 6 of 7
