Chapter 2, Problem 25P
(II) A car moving in a straight line starts at x = 0 at t = 0. It passes the point x = 25.0 m with a speed of 11.0 m/s at t = 3.00 s. It passes the point x = 385 m with a speed of 45.0 m/s at t = 20.0 s. Find (a) the average velocity and (b) the average acceleration between t = 3.00 s and t = 20.0 s.

#4) A baseball is launched by mechanical means nearly vertically upward from a point near the edge of
the roof of Morrow Library. It just misses the edge of the roof on the way down (when it is in free fall)
and passes a point a distance 10.0 m below its starting point at a time 4.75 s. Air resistance may be
ignored. Use the magnitude of the acceleration due to gravity as 9.80m/s² and report answers to 3 sig
figs for parts A-E. Consider this as a one-dimensional problem. Show starting equations, do algebra first,
and then plug numbers in last for each part.
