The time it takes to hit the ground can be calculated using the equation t = √(2h/g), where t is the time in seconds, h is the height in meters, and g is the acceleration due to gravity (9.8 m/s²).
No, the mass of an object does not affect the time it takes to hit the ground. This is because the acceleration due to gravity is constant for all objects, regardless of their mass.
Air resistance can affect the time it takes to hit the ground by slowing down the object's descent. This is because air resistance creates a force that opposes the object's motion, causing it to take longer to reach the ground.
Yes, the time it takes to hit the ground can be different on different planets. This is because the acceleration due to gravity is different on each planet, depending on its mass and radius.
The initial velocity can affect the time it takes to hit the ground by increasing or decreasing the object's speed. This can result in a shorter or longer time to reach the ground, depending on the direction and magnitude of the initial velocity.
