ASSUME FRICTIONLESS, HORIZONTAL MOTION
ASSUME ALL SPRINGS ARE INITIALLY AT THEIR RELAXED LENGTH
A 0.01kg object is initially sliding at 9.0 m/s.
It goes up a ramp (increasing its elevation by 1.5 m), and then
moves horizontally before striking a spring of force constant
k
= 100 N/m.
The spring is compressed by 5.0
cm as it completely stops the object.
1)
How much heat energy was created during this motion?
A 5kg block is dropped from rest from a point 5.0 m above the top of a spring of
force constant
k
= 800 N/m, as shown at right.
