I need help answering this question..I can't find any examples similar to help me out.
A rock of mass 6.0 kg travels with uniform speed at the end of string that can withstand a maximum tension of 75 N before breaking. With what maximum speed can it travel if the radius of the circle is 1.5 m?
Offline
tension = m(v^2)/r + mg
75 N = (6kg(v^2)/1.5 meter) + 6kg(10 m/s^2)
v= 1.936 meter/second
