Little g Gravity

“A rock is dropped from a height of 45 meters. Calculate the time it takes for the rock to hit the ground, assuming no air resistance. Show all work and explain how gravitational force influences the rock's motion. A feather and a hammer are dropped simultaneously from the same height in a vacuum. Describe the motion of both objects as they fall to the ground, including the role of gravitational force. Explain how this scenario aligns with Newton's laws of motion.”
