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 mevery 5.00 s and rises vertically at a rate of 3.00 m/s.

1.

Find the speed of the bird relative to the ground.

Express your answer using three significant figures.

2.

Find the magnitude of the bird's acceleration.

Express your answer using three significant figures.

3.

Find the direction of the bird's acceleration.

Express your answer using one significant figure.

4.

Find the angle between the bird's velocity vector and the horizontal.

Express your answer using three significant figures.

In a volcanic eruption, a 2.40 × 103 kg boulder is thrown vertically upward into the air. At its highest point, it suddenly explodes (due to trapped gases) into two fragments, one being three times the mass of the other. The lighter fragment starts out with only horizontal velocity and lands 340 m directly north of the point of the explosion. Part A: Where will the other fragment land? Neglect any air resistance. Express your answer using three significant figures....
