Module 1: Vectors
Review of Vectors
As described in the PHY1321 lecture, a
vector A can be used to represent any
quantity having both magnitude and
direction (as opposed to scalars, which
have magnitude only.) So when

Module 5: Energy
In the block-spring system shown
below, a 0.80-kg block is given an initial
velocity 1.2 m/s to the right and
collides with a spring of negligible mass
whose force constant is = 50 /.
(a) Calculate the
Module 8: Angular Momentum
A projectile of mass moves to the right with a
speed , as shown at right. The projectile strikes
and sticks to the end of a frictionless axle of mass
perpendicular to the
Module 3: Range Equation
The Range Equation relates the range a projectile travels to its initial velocity, ,
and its launch angle according to the equation

Note that answers to these questions are located in the back of the text after the appendices.
Recall from our brief discussion of differential calculus that differentiation allows
us to analyze the instantaneous rate of change of a function relative to its
independent variable. Thus if the position of a particle varies as
