- A hawk flies in a horizontal arc of radius 13.6 m at a constant speed 3.60 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 3.60 m/s. magnitude m/s² direction from the direction of velocity towards center of the circleDon't provide handwritten solution.6) You push a ball off a desk so that it rolls with a constant velocity of 5 m/s. If the desk is 2 m off the ground, a) How far horizontally will the ball travel before hitting the ground? b) What is its velocity in vector form at the instant right before it hits the ground? What angle does the velocity make with the x-axis?

- 2bb). Thank you in advance for your quick help. A car leaves a stop sign and exhibits a constant acceleration of 0.50 m/s2 parallel to the roadway. The car passes over a rise in the roadway such that the top of the rise is shaped like an arc of a circle of radius 500 m. At the moment the car is at the top of the rise, its velocity vector is horizontal and has a magnitude of 6.00 m/s. What are the magnitude and direction of the total accelerationvector for the car at this instant?please help with this questionQuestion 2 1) An arm OA rotates around the origin O according to the angle 0 2 0.15t where @ is in radians and t in seconds.
