A 30 kg launching machine fires a 250 gram projectile horizontally at 100 m/s. This causes the machine to slide backward 1.122 meters before coming to a rest.
a) What is the machine's velocity?
b) How long did it take to go the 1.122 meters?
c) What was the momentum of the machine?
d) What was the force necessary to move this machine?
e) What was its acceleration during this time?
f) What is the coefficient of kinetic friction?
g) What surfaces are likely to cause this friction?
h) IF this was on the moon, and all else was the same, how far would this machine slide?
