Question
![A super ball of mass 0.1 kg is dropped from a height of 3.0 m above the floor.
It bounces off the table and rises to a height of 2.6 m. This is an elastic col-
lision similar to the carts with springs in your lab.
Calculate the velocity of the ball the instant before it reached ground
level, v,.
a.
Hint: You can use conservation of
mechanical energy and the height it is
dropped from to get this velocity.
h;=3m
330.1kg
N;=0
%3D
+y
DIRECTION
3.0
Now use conservation of energy
to calculate the velocity the ball
must have after the collision at the
instant it leaves the ground to reach
a height of 2.6 m.
Figure 8-21
с.
These velocities are the initial and final velocities for the collision with
the ground. Use them to calculate the change in momentum of the
ball. Don't forget the directions are not the same so one will be +, the
other -.
