INSTRUCTOR: PROF. GREG ANDERSON
Problem
A cat is gently tossed upward at 10ft/sec from atop a 100ft building. Find the
cat's position at time t until she hits the big soft pile of yarn at the base of the
building. (No cats are harmed in this experiment!) Take for granted that the
terminal velocity for cats is 80 ft/sec. Furthermore, without correcting for the
height of the yarn pile (which is perfectly adequate to keep kitty comfortable),
estimate the time and velocity of impact.
Solution
Since
0.4
1

80
ft

= 32
