Joe and Mary are hiking and come by a cave that goes straight down. Joe wants to know how deep the cave goes. So he drops a large rock off the cliff and measures the time it takes to reach the bottom. He hears the rock hit the water below in the cave about 6.3 seconds later. How deep is the cliff?

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Problem #1
Joe and Mary are hiking and come by a cave that goes
straight down. Joe wants to know how deep the cave goes. So
he drops a large rock off the cliff and measures the time it takes
to reach the bottom. He hears the rock hit the water below in
the cave about 6.3 seconds later. How deep is the cliff?

Example 14 The uniform circular disk has a mass of 7.6 kg and a radius of 0.6m The disk is suspended from a pin at A and can rotate freely about A. The pin is connected to a horizontal plate on smail wheels. At the instant t = 0 a force is applied to the plate (which is initially at rest), so that it accelerates at a 1.5 m/s² (towards the right). Now calculate the horizontal and vertical components of the reaction at A and the magnitude of angular acceleration of the plate at the instant t = Os.
