A hawk flies in a horizontal arc of radius 11.9 m at a constant
speed 3.95 m/s.
(a) Find its centripetal acceleration. m/s2
(b) It continues to fly along the same horizontal arc but
increases its speed at the rate of 1.50 m/s2. Find the acceleration
in this situation at the moment the hawk's speed is 3.95 m/s.
magnitude___________ m/s2 ________ direction ° from the
direction of velocity towards center of the circle
2 A car initially traveling at 29.2 m/s slows
down with a constant acceleration of
magnitude 1.80 m/s2 after its brakes are
applied.
(a) How many revolutions does each tire make before the car
comes to a stop, assuming the car does not skid and the tires have
radii of 0.345 m?
(b) What is the angular speed of the wheels when the car has
traveled half the total distance?


(b) What is the angular speed of the wheels when the car has
traveled half the total distance?
