A hawk flies in a horizontal arc of radius 12.0 m at a constant speed of 7.1 m/s. It continues to fly along the same horizontal arc but increases its speed at the rate of 7.9m/s2. Find the acceleration magnitude under these conditions.
It is common to see birds of prey rising upward on thermals. The paths they take may be spiral-like. You can model the spiral motion as uniform circular motion combined with a constant upward velocity. Assume a bird completes a circle of radius 6.00 m every 5.00 s and rises vertically at a constant rate of 3.00 m/s. Determine the speed of the bird relative to the ground.
A shot putter releases the shot some distance above the level
ground with a velocity of 12.0 m/s, 51.0° above the horizontal. The shot hits the ground 2.08 s later. Ignore air resistance. (a) What are the components of the shot’s acceleration while in flight? (b) What are the components of the shot’s velocity at the beginning and at the end of its trajectory? (c) How far did she throw the shot horizontally? (d) Why does the expression for R in Example 3.8 not give the correct answer for part (c)? (e) How high was the shot above the ground when she released it? (f) Draw x-t, y-t, vx-t, and vy-t graphs for the motion
