How fast should you throw an apple so it can reach 6m in the air?

To determine the speed needed to throw an Apple to reach a height of 6 meters, we can use the physics of projectile motion. The formula to calculate the initial velocity (v) required to reach a certain height (h) is ( v = \sqrt{2gh} ), where ( g ) is the acceleration due to gravity (approximately 9.81 m/s²). Plugging in the values, ( v = \sqrt{2 \times 9.81 , \text{m/s}^2 \times 6 , \text{m}} \approx 10.8 , \text{m/s} ). Thus, you should throw the Apple at an initial speed of about 10.8 m/s to reach a height of 6 meters.
