Purpose:
The purpose of this lab is to test projectile motion, and to show that motion is independent of the
mass projectile, so to do this we decided to look at the kinematics
A cumin canister of mass m = 0.40 kg slides across a horizontal
frictionless counter with speed v = 0.50 m/s. It then runs into and
compresses a spring of spring constant k = 750 N/m. When the
canister is momentarily stopped by the spring, by what distanc

A car has initial speed v0: 10.0 m/s. How far does a car take to
slide to a stop on a horizontal road if the coefficient of kinetic

Curved portions of highways are always banked (tilted) to prevent
cars from sliding off the highway. When a highway is dry, the
frictional force between the tires and the road surface may be
enough to prevent sliding. When the highway is wet, however, the
