When a ball is thrown, the horizontal distance travelled, d, in metres, can be modelled by the equation 2² d= sin 20, where 8 = 9.8, v is the velocity with which the ball is thrown, in metres per second, and is the S angle of elevation, in radians. If a ball is thrown at 10 m/s, what angle of elevation is required for the ball to travel 15 m? ✓✓✓✓
