an object is dropped from a cliff. after 3 seconds, its acceleration is _____ m/s 2

Answers

Answer 1

According to the question, The acceleration of an object in free fall near the surface of the Earth is approximately 9.8 m/s².

When an object is dropped from a cliff, it experiences gravitational acceleration directed towards the Earth. This acceleration is constant and equal to the acceleration due to gravity, which is approximately 9.8 m/s² near the surface of the Earth. Therefore, after 3 seconds, the acceleration of the object will still be approximately 9.8 m/s². The acceleration remains constant unless other forces, such as air resistance, come into play. This is because the acceleration due to gravity remains constant unless other forces, such as air resistance, significantly affect the motion.
