Drop-tubes are used to simulate weightlessness for various experiments.
The experiment container is stopped at the bottom of the tube by a spring
and damper. Since the equipment can be quite delicate, the deceleration
of the container, and hence its motion, is very important.
What is known:
- container mass m = 17 kg
- impact velocity v = 13 m/s
- spring constant k = 715 N/m
- damper constant c = 100 N-s/m
