(A.)
A hawk flies in a horizontal arc of radius
13.4 m at a constant speed of 4.5 m/s.
Find its centripetal acceleration.
Answer in units of m/s2.

(B.)
It continues to fly along the same horizon-
tal arc but increases its speed at the rate of
1.45 m/s2.
Find the magnitude of acceleration under
these new conditions.
Answer in units of m/s2.
