Review: Chapter 2.93.8
The purpose of this review is to refresh your memory. Physics is a cumulative subject, so make it
sure you understand basic concepts and typical problem solving techniques in previous chapters
before moving on to a new chapter!

A. Free Fall
A ball is shot vertically upward from the surface of another planet. A plot of
y
versus
t
for the ball is
shown below, where
y
is the height of the ball above the starting point and
t
= 0 at the instant the bal
is shot. The figure’s vertical scaling is set by
y
s
= 60 m. Find the magnitude of the free fall
acceleration of the planet and the initial velocity of the ball.
B. Vectors
In the figure
a
and
b
have magnitudes of 4 m and 3 m, respectively. The angles in the figure are
θ
1
=
30º and
θ
2
= 100º. Find the angle and magnitude of the sum of the two vectors.
