Pre-Lab Assignment
Momentum and Energy
Name
1. An air track glider of mass mi = 0.200 kg moving at 0.750 m/s has a perfectly inelastic
collision with a glider of mass m2 = 0.400 kg at rest.
a) What is the initial momentum of the glider?
b) What is the final velocity of the gliders?
c) Calculate the initial kinetic energy of glider and the final
kinetic energy of the combined gliders.
2. A 1/2 kg cart, initially at rest, is pulled on a frictionless surface by a 2 N force for just 2
seconds. It then travels on the frictionless surface for 4 additional seconds. It encounters a
rough stretch of track causing it to stop in 6 additional seconds. Plot the acceleration,
velocity, and momentum graphs of the cart with numerical magnitudes for this scenario.

- = 4 mls ?
from *= 2sec to *= 6 sec,
a , =0
as no force is acting.
from * = 6 sec to t= 12 sec.
velocity at t= 6sec = velocity at t= 2second
v =...
