Q. Katie and Emily are riding on a circular merry-go-round that has a radius of 5m. Katie is on a horse that is 2.5m from the center of merry-go-round and Emily is on a tiger that is 4.5 m from the center of the merry-go-round. What is Katie's tangential velocity (in m/s) if her angular velocity is 0.5rad/s?

Q. Q. At 20 degrees C, a rod is 20.05 cm long on a steel ruler. Both rod and ruler are placed in an oven at 270 degrees C, where the rod now measures 20.11 cm on the same ruler. What is the coefficient of linear expansion for the material of which the rod is made? Steel =11x10^-6.
