What is the mass of the object? F=10 N; V= 2.0 m/s; r= 3.0 m.?
a force of 10 n applied to one end of a cord keeps an object tied to the other end moving at a speed of 2.0 m/s in a horizontal circle of radius 3.0 m. What is the mass of the object?

for the moving object, force acting is
F = m v’2 / r , so that
mass of the object is m = F r / v’2 = 10x3/ 4 = 7.5 kg.

F = m v^2 / r
m = F r / v^2
m = 10 * 3 / 4 = 22.5 kg
