Free Fall and Vertical Velocity: Solving for Time at Same Level

In summary, free fall is a type of motion where an object falls under the influence of gravity without any external forces. It differs from other types of motion in that only gravity is acting on the object. The acceleration of an object in free fall is equal to the acceleration due to gravity, which is approximately 9.8 meters per second squared. The acceleration is constant as long as there are no other external forces. The mass of an object does not affect its free fall, as all objects experience the same acceleration due to gravity.

An object is thrown vertically up from the top of a tower with an initial velocity of 29.4m/s. Four seconds later another object is drop from the top of the tower. How many seconds will the two be at the same level?



I'm trying to solve it for a day already. Sorry, I suck at this :P

Well, try coming up with functions for position in terms of time using our basic laws of kinematics. Then set the two equal and solve.
 

Related to Free Fall and Vertical Velocity: Solving for Time at Same Level

1. What is free fall?

Free fall is a type of motion in which an object falls freely under the influence of gravity, without any other external forces acting on it.

2. How is free fall different from other types of motion?

In free fall, the only force acting on the object is gravity, whereas in other types of motion, there may be other forces such as friction or air resistance.

3. What is the acceleration of an object in free fall?

The acceleration of an object in free fall is equal to the acceleration due to gravity, which is approximately 9.8 meters per second squared near the Earth's surface.

4. Is the acceleration of an object in free fall constant?

Yes, the acceleration of an object in free fall is constant as long as there are no other external forces acting on it.

5. How does the mass of an object affect its free fall?

The mass of an object does not affect its free fall. All objects, regardless of their mass, will experience the same acceleration due to gravity in free fall.
