Answer:
bobby has a greater magnitude of velocity because because when angular speed is constant linear velocity is proportional to radius of the circular path
B. They both have same magnitude of angular velocity since the angular speed of the merrygoround is constant
C. Also they both have the same tangential acceleration because the angular speed is constant and tangential is zero for both of them
D. Centripetal acceleration of Bobby is greater
E.they both have the same angular acceleration because angular Speed I constant so angular acceleration is zero for both

Answer:
The value is 
Explanation:
From the question we are told that
The depth of the mountain is
Generally the velocity of the surface wave is mathematically represented as
=>
=> 
Generally using the Froude number is mathematically represented as

Here V is the velocity of the current
Given that the waves do not travel upstream, then the flow of the current is supercritical which means that

=> 
=> 
Hence the minimum velocity of the current is

This because the velocity of the current is greater velocity of the surface wave , so minimum will be like the lowest possible value of V which is v
