I have no idea how to do this 1. Some birds endure tremendous accelerations as they dig insects out of trees. A bird's beak
can be moving as fast as 5.8 m/s [forward](almost 21 km/h), but its speed is reduced to zero
within 0.0059 s by the impact with a tree.
a. What acceleration does the bird's brain withstand?
b. How far into the tree bark does the bird's beak travel as it stops?

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?

Which type of bond is found between the atoms of a molecule? a. metallic b. delocalized electron c. covalent d. ionic

The earth is constantly spinning on its axis, like you might spin a basketball on your finger. it is this spinning of the earth that causes
