Hint: No calculation needed here. The acceleration of any object in freefall is the same. (What's the acceleration due to gravity?)sarah_615 said:What is the acceleration of the ball?
Free-fall kinematics refers to the study of the motion of an object under the influence of gravity alone, with no other forces acting on it.
To find the acceleration of an object in free-fall kinematics, you can use the equation a = g, where g is the acceleration due to gravity (9.8 m/s^2 on Earth). This equation assumes that there are no other forces acting on the object.
The equation for solving free-fall kinematics for acceleration is a = (vf - vi)/t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.
To find the initial speed of an object in free-fall kinematics, you can use the equation vi = vf - at, where vi is initial velocity, vf is final velocity, a is acceleration, and t is time.
Solving free-fall kinematics can be applied to various real-world scenarios, such as calculating the speed and acceleration of a skydiver, determining the trajectory of a projectile, or understanding the motion of objects falling from a height. It is also important in engineering and physics to design and analyze structures and machines that are subject to gravity.
