adminI found ##0.25m/s## and ##0.125″rad/s”##.
The linear speed will be: ##v=”distance”/”time”=5/20=0.25m/s## The angular speed is: ##omega=”angle”/”time”=theta/t## but…how do we find the angle described by our object???? We know that between radius, ##r##, angle ##theta## (in radians) and arc length ##s## there is a relationship as: ##s=rtheta## so ##theta=s/r=5/2##rad Finally then: ##omega=(5/2)/20=0.125″rad/s”##
The two speeds are also connected through the radius as: ##v=omega*r##…try it!!! 🙂
