A hawk flies in a horizontal arc of radius 13.3 m at a constant speed 3.20 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 1.15 m/s2. Find the acceleration in this situation at the moment the hawk's speed is 3.20 m/s. magnitude m/s? ° from the direction of velocity towards center of the circle direction

A football quarterback shows off his skill by throwing a pass 46.00 m downfield and into a bucket. The quarterback consistently launches the ball at 37.00° above horizontal, and the bucket is placed at the same level from which the ball is thrown.

an airplane flies between two points on the ground that a re 500km apart. the destination is directly north of the origination. The plane flies with an air speed of 120 m/s. if a constant wind blows at 10.0 m/s. due west during the flight, what direction must the plane fly relative to the north to arrive at the destination.
