The time until an object hits the ground is calculated using the equation t = √(2h/g), where t is the time in seconds, h is the height of the object in meters, and g is the acceleration due to gravity (9.8 m/s²).
No, the mass of the object does not affect the time until it hits the ground. The equation only takes into account the height and acceleration due to gravity.
Yes, the time until an object hits the ground is independent of its initial velocity. The equation only considers the height and acceleration due to gravity.
The equation for calculating the time until an object hits the ground is accurate for objects in free fall under the influence of gravity. However, it may not be as accurate for objects with air resistance or for objects in non-uniform gravitational fields.
Yes, the equation can be used for objects on different planets as long as the acceleration due to gravity is known. The acceleration due to gravity varies from planet to planet and can be substituted into the equation to calculate the time until an object hits the ground on that specific planet.
