Final answer:
The centripetal force on the rock is approximately 394.79 N.
Step-by-step explanation:
The centripetal force on the rock can be found using the formula:
Centripetal force = (mass * velocity^2) / radius
Given that the mass of the rock is 1kg, the velocity is (100 rounds/1 minute) * (2π radians/round), and the radius is 1 meter, we can substitute these values into the formula to calculate the centripetal force.
Centripetal force = (1kg * ((100 rounds/1 minute) * (2π radians/round))^2) / 1 meter
After evaluating the expression, the centripetal force on the rock is equal to (approximately): 394.79 N.
