Professional baseball player Nolan Ryan could pitch a baseball at approximately 160.0 km/h. At that average velocity, how long did it take a ball thrown by Ryan to reach home plate, which is 18.4 m from the pitcher’s mound? Compare this with the average reaction time of a human to a visual stimulus, which is 0.25 s.
My pug/bulldog mix, Georgia, who is blind and deaf, gets a whiff of her dinner. As soon as it registers to her that it's dinnertime, she runs 4.12 meters from the middle of our living room to our kitchen, where she is satiated with her grub. If it takes her 4.45 s to get to the kitchen, what was her speed in m/s to the nearest hundredth?

You attach a meter stick to an oak tree, such that the top of the meter stick is 2.072 meters above the ground. Later, an acorn falls from somewhere higher up in the tree. If the acorn takes 0.151 seconds to pass the length of the meter stick, how high ℎ0above the ground was the acorn before it fell, assuming that the acorn did not run into any branches or leaves on the way down?
A dolphin in an aquatic show jumps straight up out of thewater at a velocity of 13.0 m/s. (a) List the knowns in thisproblem. (b) How high does his body rise above the water?To solve this part, first note that the final velocity is now aknown and identify its value. Then identify the unknown, anddiscuss how you chose the appropriate equation to solve forit. After choosing the equation, show your steps in solving forthe unknown, checking units, and discuss whether the answeris reasonable. (c) How long is the dolphin in the air? Neglectany effects due to his size or orientation
