Sample Problem
A mass of 3 kg is swung in a horizontal circle attached to a rope of length 2m.
If the speed of the mass is 10 m/s, what is the acceleration?
Force on the mass due to the rope?
If the rope were twice as long and the mass completed a circle in the same amount of time, would the acceleration of the mass be larger, smaller, or the same.
What law(s) or principle(s) does this problem illustrate?
