# Rotation: tension and tangential velocity

** Please see the attached file for the complete solution response **

Please provide me step by step solution.

A mass (M=3kg) is attached to a weightless cord of length L=2m is spun in a circular path. θ=85Â°.

a) Draw the free body diagram for the mass at the point in time shown in the figure above.

b) What is the tension in the cord?

FT=_______________

c) What is the tangential velocity of the mass?

vtan=_______________

d) How long does it take the mass to make one full rotation?

T=_______________
