A 2kg object is tied to a cord and swung in a horizontal circle of radius 1 m with a frequency of 1.333 Hz. What is the linear speed?

Please help!!

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
