The minimum speed required for the rock to just make it around the top of the vertical circle is determined by the need to maintain sufficient centripetal force at the top of the circle. At the top, the gravitational force must provide the necessary centripetal force to keep the rock in circular motion. The minimum speed ( v ) can be calculated using the formula ( v = \sqrt{g \cdot r} ), where ( g ) is the acceleration due to gravity (approximately 9.81 m/s²) and ( r ) is the radius of the circle (1 meter). Thus, the minimum speed is about 3.13 m/s.
