An astronaut on the Moon, where there is no air resistance, throws a ball. The ball's initial velocity has a vertical component of 8.00 m s⁻¹ and a horizontal component of 4.00 m s⁻¹, as shown. [Figure 6.1] The acceleration of free fall on the Moon is 1.62 m s⁻². What is the speed of the ball 9.00 s after being thrown?
