It continues to fly along the same horizontal arc but increases its speed at the rate of 0.66 m/s 2 . Find the magnitude of acceleration under these new conditions. Answer in units of m/s 2 .

Complete Question

A hawk flies in a horizontal arc of radius 12.0 m at constant speed 4.00 m/s. (a) Find its centripetal acceleration. (b) It continues to fly along the same horizontal arc, but increases its speed at the rate of 1.20 m/s 2 . Find the acceleration (magnitude and direction) in this situation at the moment the hawk

a

b

direction   with the horizontal

Explanation:

From the question we are told that

   The radius is  

  The the speed is  

  The tangential acceleration is  

Generally the centripetal acceleration is mathematically represented as

=>  

=>  

Gnerally the resultant acceleration is mathematically represented as

=>  

=>  

Generally the direction is mathematically represented as

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true
