Part 1. When a ball is thrown, the horizontal distance travelled, f. in metres, can be modelled by the equation d- - 26, where R - 9.8 8 7. vis 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 eagle of elevation is required for the ball to travel 40 m? 2. A triangular ramp is built with an incline angle of . If the base of the ramp is I m in length, determine the exact value for the height of the ramp. Show all shops
