I need to find the height a rocket travels(bottle rocket). If I use this equation, ignoring air resistance, etc... I should use a stop watch from the time of launch till it hits the ground equaling t. a=9.81 m/s.(adsbygoogle = window.adsbygoogle || []).push({});

Is that the correct way to use the formula for this excerise?

Is there another way I should use it?

Is there another formula or method to find the height?, if so what?

--Thanks
