Worst Ride Ever
At the fair, someone decided to make a ride where the
passengers are attached to a large spring and set
oscillating vertically. The passengers oscillate with an
amplitude of 5.5 meters and a period of 1.2 seconds.

Chapter 48: Friction
When a body is in motion on a rough surface it feels a
sliding friction called kinetic friction.
The force of kinetic friction acts always opposite the
motion.
The magnitude of the kinetic friction depends on bot

Chap 3-8: Relative Velocity:
We already considered relative speed in one
dimension; it is similar in two dimensions except
that we must add and subtract velocities as
vectors.
Each velocity is labeled rst with the object, and second
