A thin rod rotates at a constant angular speed. In case A the axis of rotation is perpendicular to the rod at its center. In case B the axis is perpendicular to the rod at one end. Explain for each case whether there are any points on the rod that have the same tangential speeds.
Suppose a bat uses sound echoes to locate its insect prey, 3.50 meter away, find the echo time for air temp 6oC.
Find the echo time for air temp of 32 degrees Celsius.
Find what percent uncertainty does this cause for the bat in locating its insect?
