Disk A weighs 1.80 lbs with a
radius of 1.20 in and is sliding on a
smooth horizontal plane (i.e., parallel to the ground) as
shown in the figure. Disk B weighs 10.9
lbs with a radius of 2.20
in and is initially at rest. The coefficient of
restitution between the two disks is 0.300
.
- What is the angle (degrees) between the positive y axis and the line of impact?
- What is the speed of disk B after the impact?
- What is the speed of disk A after the impact?
- How much kinetic energy is lost in the collision?
- What percentage of the original kinetic energy is lost in the collision?
