Correct Answer--------------------v= -1 m/s
A city has streets laid out in a square grid, with each block 135 m long. If you drive
north for three blocks, then west for two blocks, how far are you from your
starting point? ------------Correct Answer--------------------d= 486.75 m

A pipe discharges storm water into a creek. Water flows horizontally out of the
pipe at 1.5 m/s, and the end of the pipe is 2.5 m above the creek. How far out
from the end of the pipe is the point where the stream of the water meets the
creek? ------------Correct Answer--------------------1.07 m
The Scion iQ is a compact car that is capable of very tight turns- it can spin around
in a circle 8.0 m in diameter. If a driver goes around such a circle at 5 m/s (a bit
faster than 10 mph), what is the magnitude of his acceleration? ------------Correct
Answer--------------------6.25 m/s^2
In a head-on collision, an infant is much safer in a child safety seat when the seat
is installed facing the rear of the car. Explain. ------------Correct Answer----------------
----His head and back rests against the padded back of the seat. In the case of the
head-on collision, the child with seat will continue to move forward at the before-
crash speed until he hits something. The back of the seat hits some object, but the
front of the seat supports the entire back and head of the child. As a result, the
force acting on the child increases a maximum value over a time interval. This
time interval is considerably better than instantaneous. Due to support of the
seat to the head of the child, there will be no whip-lash.
