BIO Woodpecker Impact When red-headed woodpeckers (Melanerpes erythrocephalus) strike the trunk of a tree, they can experience an acceleration ten times greater than the acceleration of gravity, or about 98.1 m/s2. What is this acceleration in ft/s2?

1. A vehicle drives at a constant speed of 215km/h for 42.3 seconds, accelerates by 29.4m/s2 for 5.00s. And finally, slows down to the stop. The entire movement takes 88.6 seconds. A. Make a vector-speed diagram or graph as a function of time for the situation. B. Determine the maximum speed. C. Determine the total displacement. 2. Two 9.82km separate trains travel on parallel tracks in opposite directions, one to the other. Train A has a speed of 5.87 km/h at departure and accelerates at a rate of 0.29m/s2. Train B has a speed of 20.3m/s at departure and an acceleration of 0.69m/s2. A. Make a diagram or graph position according to time for the situation. B. Determine when trains meet.
9. Use the following information for parts a-b. A peregrine falcon drops from rest off the top of the Stantec Tower, which is 250.8 m tall. It accelerates in the downward direction due to gravity at a rate of 9.81 m/s² (assume no air resistance). a) How long did it take the peregrine falcon to reach the ground? cquired
